You can find documentation around on iproute, I think it was the lartc.org site I used for reference. As the integration with Fedora network scripts I think there is no way to have such a complex configuration in a clean system. This is on Fedora 9, but I doubt things are improved in this field in newer version, considering the rampant NetworkManager-style approach to networks. In my case I have the ifcfg scripts doing some basic configuration which will not enable significant traffic (for example forwarding=0, no routing, no default gw). Then I have a custom script called by rc.local which does everything: iptables firewalling, iptables MARKing based on --match conntrack, ip route routing based on fwmark. I tried to achieve external visibility on both my public IP addresses for incoming connections, but something is still not working; it looks like there is a problem with the tracking of the incoming connection because it is not established yet. I stopped spending time in fixing this, as my target was to have the fail-over part working.

First thing: disconnect your two 1TB drives where you have your data. Second: try to fix the system when using only the 2 200GB disks. Losing the system will be bad, losing the data would be worse. When the system is OK again, you reconnect the data drive and make them available. When you have big drives/partitions, it is often a good idea to remove them from /etc/fstab before upgrading. Why should the upgrade progress have the filesystem with all my photos dangerously mounted? -- Roberto Ragusamail at robertoragusa.it -- fedora-list mailing list fedora-list@redhat.com To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines

Kudos to the KDE guys who go beyond small fixes and actually push

Upgrading PA like this involves big changes and does not qualify as
either security nor as small other bug fixes.
If you want a newer PA I'd recommend doing the upgrade from F10 to F11.
Not a good reason to upgrade.
Actually I don't want a newer PA, just a working PA.

Re: RAID 1 error question - boot problem.
Robin Laing wrote: /dev/sda1 ext3 boot /dev/sda2 ext3 / raid /dev/sdb1 Swap /dev/sdb2 Unknown / raid Running mdadm /dev/sdb2 --examine shows that the partition superblock is showing RAID 1 and that it is clean. If sda2 and sdb2 are part of a RAID-1 they should be identical. The fsck should give the same result on both, but sdb2 is not even recognized as ext3. I do not know exactly the meaning of what you have pasted, but I suppose that ext3 and unknown is from content autodetection and raid is from partition type (0xfd). So you should have an md device (md0?) composed by sda2 and sdb2, which is not happening. As this is a critical system, it is a priority and is being used as a virtual server. With only the second drive installed, we tried to run fsck.ext3 on the /dev/sda2 (normally b2) with no success. We also tried /dev/md0 as Ubuntu has created the /dev/md0 from the single drive. So something is wrong on sdb2. If sda2 is good, you should just get the RAID working on one drive (degraded mode) and then readd the sdb2 to the mirror. The user has not tried to boot with only the one drive in yet. He is making a copy of the drive on a different system. Now, the question. On booting from a mirror 1 array, if there is a problem with the raid system, how does the boot process read the mdadm.conf file when it is on the RAID array that needs to be created? Is there some data that is stored in the /boot or someplace else that has the necessary info to tell the system how to build the array? It will not read mdadm.conf. The info is in the superblocks of the partitions. Is it part of the /boot/grub/device.map or /boot/System.map* ? No. Just superblocks, and possibly the initrd image you boot from. Any suggestions to where to start? Boot from a live cd and do: fdisk -l /dev/sda fdisk -l /dev/sdb blkid /dev/sda1 blkid /dev/sda2 blkid /dev/sdb1 blkid /dev/sdb2 cat /proc/mdstat dmesg|less fsck /dev/sda2 (but do not let it modify anything) fsck /dev/sdb2 (but do not let it modify anything) fsck /dev/md0(but do not let it modify anything) these will give you more info to understand what's happening.

It is a little puzzling that when someone asks on a fedora ML how to upgrade Fedora, the answer is often upgrade to CentOS instead. Apart from the dangerous reinforcement of the Fedora is not for real stuff myth, I wonder why CentOS (or RHEL), which are based on Fedora can upgrade Fedora-CentOS when Fedora can not guarantee Fedora-Fedora. I mean, if there are scripts to convert inittab to upstart, etc., they take life in Fedora and then are included in RHEL, right? Another thing I'm not convinced about is the DVD or yum upgrade choice. Once upon a time, the DVD (the CD) was the way. Not anymore; there are proposal about removing the DVD upgrade option. So... let's use yum. But it can't do everything anaconda can, so this is at your risk too. Are we going the path to an unupgradable Fedora?

Re: Upgrade from FC6 to FC11
Jussi Lehtola wrote: The reason is that RHEL 5 is based on Fedora 6, so the upgrade should work out smoothly. This also means I'm almost not really upgrading anything. FC5-CentOS5 is similar to FC5-F6 (ok, with some backports, I know) Also if you haven't updated the machine so far, it's best to update to a distribution that still has many years of support to come. The software you have installed manually in FC5 should still work in CentOS 5. I have no manually installed software. One of the reason to prefer Fedora (possibly a recent one) is that the software I need has been already properly packaged with high probability. If, on the other hand, you really want to stick with Fedora, I'd do a complete reinstall since that is the quickest way to do the upgrade (doing 4 upgrades is *really* slow). Besides, that way you get a clean system and all of the advantages of the new ext4 file system. In my specific case, converting the system disks brings no advantage as they are never really accessed. As regards the data disks instead (this are fileservers in a rack), I would certainly avoid ext4 for some time for safety. The data is currently on reiserfs, whose quality is often estimated a lot worse than the actual thruth. If you want to try your luck with the successive upgrades, you still might end up with a bit of a broken system, since you will probably have to recompile the software you have installed manually. Plus, you might end up with some trouble with the upgrades themselves. I'm actually considering a 5 to 11 upgrade by DVD. I hate reinstalling. Doing it in many steps would probably not be much better. Some initrd issues, rpmsave/rpmnew cleanup etc are not a problem for me. Graphical login is almost unused, so I don't think something awful can happen for apps I'm interested in: ntp, samba, netatalk, cups. The system is on RAIDed disks, so I will disconnect one of them as an easy rollback chance in case of unresolvable issues. The machines are actually not mine and they are used in production. This is why I'm didn't upgrade in the past (except FC4-FC5).

Buffers are not always dirty data. After a sync command you don't see them drop to zero. Even if they were dirty data, it can make sense to store them sequentially and compressed, instead of writing them in the right places (which could involve many many seeks). I'm perfectly aware that they will have to be properly written after resuming, but if I say hibernate I want the machine to hibernate as soon as possible, not to force the execution of any pending activity. I would run sync before hibernation, if I wanted to write dirty buffers (in any case, suspending scripts often do sync themselves before starting). That is one of the really good things which only tuxonice has. I hope you're remembering that wrong, if it's going to be written to disk there's no benefit to doing a lot now so you can slow the restore and then do all that i/o anyway. You can make the argument for cache, at least you might save so i/o after resume. I rechecked on the net just now, and tuxonice does indeed save buffers and cached by default. I hope to see it finally merged. Don't hold your breath, for years I kept pointing out issue with suspend and being told stop whining and send patches, and I would say the patch is suspend2. It's been renamed, but still mostly not merged, and new bugs have been added. I used suspend2/tuxonice a few years ago and found it really good. The official suspend stuff never really worked. Nowadays I'm only using suspend-to-ram (damned Nvidia proprietary crap). so it's really hard to guess how much swap will actually be used. But it is really simple to decide the size of the swap partition: use a big one. There is really no disadvantage to have a bigger one. 2 GB RAM? - 5 GB swap more than enough to have 1gb swap used and suspend everything; probably large enough even when you upgrade to 4 GB RAM. I don't think anyone really cares about 2 or 3 GB of disk on a modern machine (having 2 GB of RAM makes it modern). Haven't done much embedded work? Think 512M RAM, 2GB non-volatile storage, maybe another bit of EAPROM for firmware. That's not Fedora, but it definitely is suspend/resume.

Re: Arranging data on the HDD
Javier Perez wrote:
Hi
I am changing FC11 from a two-HDD setup to a larger one-HDD setup. The
first setup is using LVM spanning both disks.
What is the best way to move everything to one HDD?
If you want to move the logical volumes from the disk couple
to the large disk, you could add the large disk to your
current LVM and then use pvmove to force the relocation of all
your stuff to the large disk. After that, you can use vgreduce
to remove the two disks from the volume group (from three disks
to one).
Also, I want to have two partitions, one for the data and one for the
programs. I know it is easy to put /home on its own partition,
but what about MySQL? I am using MythTV and both MySQL and MythTV use
/var/lib to store their data.
I'd rather not use hard links ln- s bla bla bla. I am doing that with
another pc and sometimes when I had trouble with LVM the
data would be written on the wrong places.
Another option would be to move the data directories for MythtV and/or
MySQL, but I'd hate to break something that other programs
are depending on.
One thing you can do is to use the bind option when mounting.
You can have something in a place you like and then have it appear
somewhere else too (in a place that the rpms like).
For example, my system has this in /etc/fstab:
/dev/sda9 /mnt/data reiserfs defaults1 3
/mnt/data/wwwoffle /var/cache/wwwoffle autobind 0 0
I'd like to hear everyone's thoughts on this, I bet I'm not the only one
doing something similar, but I guess this is kind of difficult
to phrase for google.
Thanks

Re: increasing time spent on grub during pm-hibernate
Konstantin Svist wrote: And it's not necessarily limited to minor corruption - the whole filesystem could get corrupted, you could lose EVERYTHING on it. Even if you just want to boot to Windows, you usually have a few different kernel versions in grub. If you chose one of those by accident, you would get this nasty surprise, too. I think that the new kernel will simply refuse to load the hibernated image and boot normally (as after an improper shutdown). Plus, even though windows rarely mounts linux partitions, linux could have easily had the windows partition mounted (to read/write the documents). Yes. But if you do not have windows partitions mounted and you hibernate and reboot to do something in windows, grub will immediately try to resume, you understand what happens and try to shutdown everything before the kernel actually runs. If you are lucky you power on again, you manage to have to grub menu shown by pressing one key and you boot windows and then resume Linux. If you are unlucky, the resume image is not usable anymore (the system has been resumed and then powered off) and you lose all the session you wanted to preserve. And that's an additional case of inexperienced users can do stupid things, so we have to block experienced users doing smart things.

Re: How do you know when a reboot is required after yum update?
Donald Russell wrote: Obviously a reboot is required when loading a new kernel But in general, does yum leave some breadcrumb clue that some other process can check? For example, maybe there's something in the package files that yum sees and creates a /rebootRequired file which is always deleted upon booting? If not, I think that'd be a cool idea.. the file could be /rebootRequired.txt and contain a plain text list of packages that caused the condition. :-) It is quite apparent that you have a Windows like mindset. I say this without any will to offend you; I just observe: 1) the reboot idea 2) the file name with lowercase and uppercase mixed 3) the file extension .txt :-) Now the serious answer. The kernel case is obvious; installing a kernel is useless without a reboot. But in other cases the new stuff will be used together with the old one. For example, replaced libs will be used by programs freshly started, and old libs will be used for programs already running. So, the reboot is not strictly required. maybe you may want to restart some services or applications. And it always depends on the specific use of the apps. Say you install a new tail command with a security related fix. Would you reboot? Maybe not. But if you have a running tail -f on some log files where things under external control may be printed? Then maybe yes. Or you just restart the logging script, right? There are some cases (glibc vulnerability for example) where a reboot could be a good idea. But, guess what, if you upgrade glibc, the sshd process will be restarted (!) as that is considered an extremely sensitive daemon. I may want to restart network facing stuff like httpd, firefox and something else, but I do not worry too much about the clock applet currently running the unfixed glibc.

Degraded means that all of the array elements aren't functional, not whether there is still redundancy. Ok, I know that, but I suppose that the refusal to upgrade on a degraded array would be do not do something dangerous when the array is not really in good conditions and then a (debatable) assumption that 4 mirrors out of 5 is an emergency condition. In my opinion this limitation is completely unjustified. RAID has as objective the system will go on; if an upgrade is impossible then the system is not going on, and it's happening for no real technical reason. I have no idea if this still applies. Yes. In your case you could have dropped the number of elements in the array, did the install and then bumped it back up again. If you only had two drives This is what I did. I did grow the array from 5 to 4 (that is, reverse-grow). you wouldn't have been able to, because anaconda also has a minimum number of drives for each raid type. So even a complete 1 element raid 1 array can't be used for an install. That is another unreasonable limitation. For example, mdadm is a little petulant if I try to create a 1-disk RAID-1, but it finally does it if I force it enough. These things are really annoying, as they happen in a particularly delicate moment, when you don't have your usual environment, you may not have an internet connection and you are already tired because of the slow DVD boot and other details. In the past I have patched anaconda to allow this. There have been RFEs both for allowing degraded arrays and allowing complete 1 element raid 1 arrays and both (well actually more since there are duplicates of these RFEs) have been closed won't fix.

I have a hint and it points to the same rpms in more than one repo hypothesis. yum -d 5 lists a lot of excluding for cost: firefox-3.0.11-1.fc10.i386 from updates excluding for cost: gnome-session-2.24.3-1.fc10.i386 from updates [...] I see something related to cost handling fixes in the yum Changelog. My guess is that elements are removed from an array one at a time and everything after that is moved back one position. Or some inefficiency of that kind. You may be able to reproduce it by configuring two updates repos. The performance change occurred between 3.2.21-2 and 3.2.22-5 based on testing on koji f10 downloads. from rpm -q -changelog yum: * Tue May 12 2009 Seth Vidal skvidal at fedoraproject.org - 3.2.22-5 from ChangeLog in yum tar.gz: 2009-04-13 James Antill ja...@and.org * yum/yumRepo.py: Fix cost sorting of repos. -- Roberto Ragusamail at robertoragusa.it -- fedora-devel-list mailing list fedora-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-devel-list
Re: F11 upgrade - worse than Windows
Simon Andrews wrote: I saw this too (but not for that long). Going into a shell I saw that anaconda was only taking ~2%CPU and that my load averages were low and that no significant data was coming in over the network, so I'm not sure what is happening over this time. I may be wrong, but I noticed in a previous upgrade that in that phase the machine is disk-limited as it is executing a great quantity of sync() functions, related to the rpm database. I would really like a simple way to turn the sync() stuff off when doing an upgrade. I know I know, it is dangerous and libeatmydata etc., but an upgrade is already considered a risk by me, so I always backup before upgrading; at that point, I would kick the sync() stuff out of the way very happily.

Re: rpm package with many files inside

There are existing bug One million files means (at 4KiB per file even if its length is one byte) about 4GiB of space on most filesystems (everyone except reiserfs, IIRC).

IMHO there is no sense whatsoever to create multiple LVM partitions on a single hard drive. You can manage with a couple small boot partitions, and the rest of stuff on LVM. When the partitions are in LVM, you can resize them whenever necessary. Let me give a different opinion on this approach. It can be useful; one day you will want to have a root for mandriva out of any LVM and you will simply kick one of the PV out of the VG and turn the partition back to native. I know there is pvresize, but I feel better when using pvmove alone (which you will probably have to use in any case before pvresize). More difficult: I want a 20 GB partition, and I'd like to have it near the fastest part of the disk (the beginning). I just kick sda6 out of the VG. Having more than one PVs has no real disadvantage, so, why not?

Therefore there is no restriction for a trusted network. So your ftp server will be available for everyone - even in a public wifi. And this is exactly what it should happen. B is trying to give permissions to some machines, but it is useless, as A is giving permission to everyone. If it were: //B if(port==(20-21) net==trusted) PERMIT; //A if(port==(20-21)) PERMIT; //default DENY; then B would give permission to some machines and A would give permission to all the others, so even if the decision process is a little different the final result is the same as before. The ftp server is available for everyone.
