I believe in the addage don't fix what ain't broken, but in the case of db3, it IS broken and my db files get corrupted on occasion. I could move to db5 or db6 OR MySQL, or even postgres. I use simple primary key files, most entries are added from a CLI or termcap/curses screen. Some programatically. With about the same number of sequential dumps vs indexed random reads. I have no experience with the c interface for postgres or mysql, but also, do not know how much the c interface has changed for sleepycat 5/6 compared to the c interface for db3, which I understand quite well. So I am prepared for a learning curve irrespective of which platform I select. Records do not exceed much more than 10-20,000, with key sizes not much wider than 16 bytes (ipv4), 13 (mac), 32 (ipv6). And various smaller key sizes. Suggestions would be very much appreciated. Well, this is essentially a bikeshed thread... so why not chip in :) I'd say it depends on what is your priority or what do you want to achieve by switching databases. If you want it to be as easy as possible, switch to DB5 and you'll be ok. If you want to learn something interesting, try one of the recent NoSQL databases, such as Redis, MongoDB or CouchDB - they're like DBx but with significantly more powerful query capabilities. If you want to get a feel of how SQL databases work, go with PostgreSQL, but be aware that to really use a SQL database the way they're made to be used, you'll need to properly design a relational schema. Using them to store 20 KiB blobs indexed by a single key is way too simplistic and probably much slower than what you could get with a simple DBx engine. Also, SQL databases usually work with SQL queries, which are text, so you'll have a non-trivial task of fitting C structs in their text/blob field types - it's best to avoid it. Also, you'll need to learn how to tune and maintain proper database servers. If you want to just try SQL but without bothering with tuning and maintainance, try SQLite, but beware it is basically limited to a single writer (and inifinite reader) clients in the best case (with WAL journalling). signature.asc Description: OpenPGP digital signature

The only problem was that particular file and messages in /var/log/messages until the Current Pending Sector counter was cleared and sector was remapped. Will it be the same (online system) with bad sector in journal area? And will it damage the filesystem? Well, SUJ is new enough that there's no general disseminated knowledge about it, but from a quick look at the code: 1) the journal recovery is only ever done in the fsck_ffs program, so it's unlikely that the kernel will panic from a bad sector 2) if the journal cannot be read at any point, the recovery code *should* offer the user to nuke the journal and perform a normal, full fsck, which presumably should leave the file system in a usable state 3) journal writes are done via the normal mechanisms, so it also shouldn't lead to kernel panics on bad sectors, but the normal cannot-write-to-device kernel error message and continued operation. signature.asc Description: OpenPGP digital signature

Neither. The best solution is to find a controller which can pass the disk as JBOD (not encapsulated as virtual disk). Failing that, I'd go with (1) (though others might disagree). Depending on the requirements and the purpose of the machine, it might idea to combine it by having the hardware handle multiple RAID-1 devices.

It is not recommended to use gjournal for small file systems (e.g.: only few gigabytes big). My question is: if I have 4 or 8 GB of RAM should I create 8 or even 16 GB journals?.. This seems huge especially if the fs size without journal is only 10 gigs. Or the recommended minimum is for systems low on RAM? You are probably missing that gjournal does full data journaling, not just metadata as is more common with other systems, so you need a journal which can hold *at least* everything you can hold in RAM, and then twice as much since one half may be replaying while other is being filled up. Even this is an estimate since it's heavily load-dependant. Or you can wait for 9.0 with metadata journaling. signature.asc Description: OpenPGP digital signature

Not exactly like RAID 0; ZFS's striping is not using regular patterns / stripes but IO balancing heuristics. This means there are no fixed stripe size but the data is distributed across the drives in a way which ZFS's algorithms predict is best. This allows for e.g. creating a zpool from a single drive, then adding another drive (as a stripe) and ZFS will use both, but new data will be written mostly to the new drive.

So, do we hide the fact, or are, in fact, not afflicted by this? Whether the data actually gets written and the on-disk cache itself flushed seems to depend on a sysctl called hw.ata.wc for FreeBSD or the dkctl setting in NetBSD; write-caching seems to always default to on because otherwise people scream bloody murder about the factor of ten reduction in write performance with it off. Further, by default (ie, FFSv2 with soft updates), data changes are synced out when you do an fsync(), but metadata changes are done asynchronously-- which is exactly what MacOS X does. In other words, if you have write-caching on, no effort is made to invoke ATA_FLUSHCACHE or SCSI SYNCHRONIZE CACHE to make sure that your disk has actually written the bits to permanent storage. To clarify: all this is in case write-caching happens on disk drives or on disk controllers. The common way to deploy servers for a long time now is to have a disk controller with RAID capabilities and its own RAM cache which is backed by a battery or a capacitor. This controller in turn switches on-drive write caches off. All of the RAID controllers I've seen have a toggle for this last part (on-drive write caches) and it was always turned off by default (though it doesn't hurt to check). To emulate this with desktop drives, as cswiger said, hw.ata.wc should be turned off, with the expected influence on drive performance. All this is valid for UFS. ZFS on the other hand *should* use BIO_FLUSH where appropriate, so it should be safer with desktop drives.

This box also acts as a network gateway so it would give an attacker carte blanche to the internal nets if it was compromised, which makes me nervous. The plan is to run openvpn as the only unjailed service and the rest of the services in a single jail or their own jails. I have never touched jails before and I'm a bit unsure of the best way to go. I realise that I can jail a service or a copy of the whole system (service would be preferable for space efficiency) but I am unclear on how to deal with IP addresses in jailed environments and if I should create individual jails or a single jail for all services. At the moment I am leaning toward a single system jail for everything so I can keep the space in which openvpn runs as uncluttered as possible and also have a single postgres instance shared by the other services. Basically, if any of the public services in the jail are compromised I would like to make it very hard for the attacker to see the internal network. Since jails can do many things there are many helper utilities that can do much to simplify the process. If you can hack python, you can, for example, modify my script at http://ivoras.sharanet.org/stuff/mkjails.py which I've used to create a thousand very light-weight jails which are started and managed using only standard FreeBSD tools. In any case, read rc.conf(5) man page for the jail_* settings. If I use this scheme must I use separate public IPs for openvpn and the services jail or is it possible to use a single IP or some NAT/PAT scheme? -this box currently has 4 x NICs split into 2x lagg interfaces in failover mode (one public, one private), if that makes any difference This is the more complex question; I think that everything which needs direct access to the NIC (i.e. BPF, DHCP, IPFW, etc.) will need to be run on the host system. TCP services will work inside jails without problems, but with jails it's almost the same as if they were on another system. If you do use NAT you will have to configure it on the host. Instead, you can also use TCP proxies (like bsdproxy). It's up to you how much complexity do you want in your system, but for simplicity I would set up a single outward-facing IP address and then proxy TCP services where I need them. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

FreeBSD's make is an integral part of the FreeBSD file system. It is not
created to be compatible across systems, but it is also not created to
prevent this kind of porting.
Wow. I disagree. It's been modified over the years to depend heavily on
a set of libraries that are available nowhere else but FreeBSD. This was
The fact that it can be compiled with gcc '-DDEFSHELLNAME=sh' -o make
*.c indicates that it in fact doesn't use any libraries except for libc...
done (from what I can see) in the name of elegance ... because the
actual functions ARE available elsewhere, but a bunch of modifications
need to be added, no possible way is it going to compile anywhere else.
Oh you're exaggerating, it's not that hard. I've made the attached patch
in about 20 minutes, and most of it is including the small lc.h ad-hoc
Linux compatibility header.
I don't claim the patched make will work perfectly but it works for
simple cases :)

I could use some help figuring out if this is a bug, and if so, where to file it. Here's the scenario: - FreeBSD 8.1-RELEASE server, sharing a ZFS filesystem via NFSv4. I think that this is the beginning of your problems - even the developer who is working on NFSv4 says it's too experimental to be used in real world. - Linux client (I've tested with RHEL 5.4 and Debian Lenny) mounting said filesystem with NFSv4. - A user on the Linux client does a Subversion checkout onto the mounted filesystem. At the end of the checkout, access to the filesystem hangs. nfsd on the FreeBSD server and rpciod on the Linux client seem to be in a tight loop, and there's lots of network traffic between them. I can reproduce this every time. The problem does not occur if the backing filesystem is UFS instead of ZFS, if NFSv3 is used instead of NFSv4, or if the client is FreeBSD instead of Linux. ... but you may have stumbled on something specific.

Re: User cpu time VS system cpu time

But keep in mind that kernel time is a broad category - while IO time in itself does not count as CPU time, file system operations for example do, because they really can be CPU intensive. Ivan, thanks for the great explanation. I think that I can measure user filesystem usage with sa - it reports number of IO operations per user/command. In which other cases kernel time is used instead of user time for a process? I do not mean all of them - just that usually occur in practice. Everything the kernel does when requested by the user is counted as kernel time - file system access, network access, getpid(), gettimeofday(), process scheduling, memory management, etc. I've noticed that there are moments when system load in top for system time is very high (60-80% while user load is 15-25%, this produces very high LA also). All processes that were run at this time show high kernel time usage, although they usually do not. System is getting back to normal after Apache restart (I think this is related to Apache shared memory somehow, but not sure). As I told you before - monitor the top line for the processes you suspect and you will get a fairly good idea what they are doing. Look at the STATE column. When you are looking at per-process statistics, the system time is also accounted. For example, if a process takes 50% of a CPU, it is possible that it takes 25% in userspace and 25% in kernel (the reverse is not true - kernel can take system CPU time without it being accounted on behalf of processes). This makes me suspect that system time in sa can not be relied on while measuring user system usage, because it notably varies under some circumstances for same operations. Am I wrong?

Re: User cpu time VS system cpu time

When some process uses many system CPU, does it really mean that process prouduces heavy load on server and takes up resources that could be used by other tasks instead? Or it only means that this process performs many waits for, say, I/O operations? In contrast to Linux (luckily), IO wait in itself in FreeBSD does not count as CPU time. Linux's iowait state is supposedly defined as idle but having outstanding IO requests but judging from performance curves in some cases I think some polling is involved. System time is time spent in the kernel - it is practically always the result of issuing kernel syscalls from userland processes. Whether it influences the overall performance of the system depends on what the processes are doing - if the machine has multiple CPU cores and the syscalls exercise those parts of the system that are parallelized then no, your process would not influence the rest of the system anymore than it would by using user time. But keep in mind that kernel time is a broad category - while IO time in itself does not count as CPU time, file system operations for example do, because they really can be CPU intensive. And by using the file system in certain ways, you really can block other processes from using it with the performance they would get otherwise. You can find out at a glance approximately what the process is doing simply by monitoring the top line for the process. There is one more thing - if the machine in question is a virtual machine, it is normal for the system time to, unfortunately, be significantly higher than it would be otherwise because of the nature of the emulation. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Mellow greetings!
On a box running FreeBSD 6.something (probably 6.4) the boot drive died.
I had never bothered to update it to 7 or 8, since I was planning to
build a new computer anyway. Since I hadn't done that yet and I still
needed the work of this machine, I just put in a new drive and installed
8.0.
The deal is that a script I restored from backup doesn't quite work as I
think it should. This is the part that somehow causes problems:
!/bin/sh
stty -echo
read -p Enter passphrase: passphrase
stty echo
main=`echo ${passphrase} | sha256 | cut -c 1-5`
if [ ${main} != ddfab ]; then
echo Wrong passphrase!
exit

I have typed the password in question about a gazillion times, so I am
pretty sure I got it right. But somehow the 'if' keeps kicking in.
There are two possible reasons for this:
1. I have Alzheimer's.
2. Something about the way sha256(1) and/or digest(1) or one of the
other commands in the script react differenly than before.
Maybe there is another reason that I just don't see?
sha256 and the like cannot change because they are standard algorithms
and changing them would break a lot of things.
Something else must be the problem. Maybe previous versions got newlines
in the $passphrase variable or something like that? You will need to
check output of every step of the script separately.

My primary use for the server (which will be in a data center) will be to run video games servers; the exact game I'll be running is based on the ioquake3 open source engine, which compiles and runs fine on FreeBSD, at least 32 bit (have not tried 64 bit FreeBSD yet, but will get around to that). My two concerns when making a decision between 32 bit and 64 bit are: 1. Performance. Will there be any difference in performance between a 64 bit OS and 32 bit on my Nehelem? Probably not so much that you would notice (i.e. not something the users would immediately feel) - for general loads we're talking about low percentages in either direction. But installing a 64-bit OS is more like planning for the future. Maybe you will need more RAM for some application and then you will be stuck with a 32-bit OS. 2. Availability of software. Will some software run only on 32 bit? Only on 64 bit? There probably are some. If you are only interested in FreeBSD ports, you can make a list of which ports you need and then inspect their Makefiles to see if there's a flag disabling them on the amd64 architecture. Another option is that you bring up a 32-bit-only jail and run your 32-bit applications from it. Additional information for Nehalems is that you should stick to the more widely available models - the 4 core+HTT ones. Some of the more exotic ones (6 core) might have problems with ULE and topology guesswork. http://suckit.blog.hu/2009/10/05/freebsd_8_is_it_worth_to_upgrade ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: VirtualBox - does it work for FreeBSD?

Yes. at is, do the guest additions work fully for those guests, or are there limitations such those I experience currently when running FreeBSD 8 as the guest? (eg no access to USB, no fullscreen mode). You are right about USB and probably about fullscreen mode. seamless mode works at least for Windows. Any major problems with a FreeBSDS host and Windows/Linux guest? You might have problems with using virtual SMP. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: hardening FreeBSD, already using GBDE

If you use a swap-backed memory drive (see http://man.freebsd.org/mdconfig) for /tmp and use geli to encrypt the swap, there would be no chance of recovery of your temporary files. I've no problem letting some poor person make a windoz machine out of my laptop -- but I don't want to share my work, my intellectual property. (I do research.) So, I'm looking for a list of changes to make, hacks really, that will further tighten up security. You did not specify anything really exact. You already encrypt your on-disk data. Do you always use encrypted network protocols like ssh and https? Strong passwords? Adequate physical security?

Re: gmirror+gjournal: spontaneous reboots on excessive disk access
Michael Grimm wrote: Hi -- I'm running a gmirror raid1 plus gjournal for a year now. This is a 7.2-RELEASE-p6 right now. Both disks are regular ATA and healthy according smartctl. Sometimes, not always though, I do experience spontaneous reboots without leaving any hints in logfiles whenver I beat my disks excessively. This might be something like: dd if=/dev/null of=/some/file bs=1M count=4k plus parallel disk accesses by mail and news server. If I omit all parallel disk access those dd's will run to completion without reboots, always. What you have is a common symptom of hardware problems - either a weak power supply or a broken disk controller. In the first case because two drives try to suck power where only one was doing it before and in the second reason because the disk controller is too broken to correctly handle simultaneous access to two drives. Unfortunately, if you don't get any console error messages it is hard to tell which. The power supply is usually easier to replace. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
