I also have STRIP= -s in my make.conf, but IIRC this should only apply to ports builds. The downside to this is if you need to do some serious troubleshooting you're screwed. On production boxen I run Release versions, and only do security updates/patches or upgrade to the next Release. In the past using the most quiescent code has been good to me. After two kernel builds/installs the huge GENERIC gets moved out of the way. My i386 box has 91MB of space used in / and the 64 bit boxen are typically about 93-95MB. I only have one i386 box left and it's crunched down kernel is 4.2MB, and my 64 bit ones average around 4.5MB. This can be an effective strategy to mitigate a / being too small, but at the cost of reducing one's ability to get down and dirty troubleshooting code bugs. -Mike ___ 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: Large discrepancy in reported disk usage on USR partition
Now that you mention it, it *is* strange that the NFS mount was not listed by the "df" function. Try again after a fresh reboot: #: df -h Filesystem SizeUsed Avail Capacity Mounted on /dev/aacd0s1a 496M176M280M39%/ devfs 1.0K1.0K 0B 100%/dev /dev/aacd0s1e 496M 15M441M 3%/tmp /dev/aacd0s1f 28G4.8G 21G19%/usr /dev/aacd0s1d 1.9G430M1.3G24%/var server2:/storage/blah/foo/data/397G103G262G28% /usr/home/development/mount/foobar I guess I must have missed the final line when copying the output when I first posted to the mailing list. And then when I replied Mel, I had already nmounted the NFS dir when attempting the suggested fix, so it did not show when I ran "df" again to double-check, and I did not realize what had happened.

Is this what you mean by avoiding Hardware > Raid? More or less. Hardware RAID has some advantages (I can dig up a mail of mine long ago outlining what the advantages were), but a lot of the time the controller acts as more of a hindrance than a benefit. I personally feel the negatives outweigh the positives, but each person has different needs and requirements. There are some controllers which work very well and provide great degrees of insights (at a disk level) under FreeBSD, and those are often what I recommend if someone wants to go that route. I make it sound like I'm the authoritative voice for what a person should or should not buy -- I'm not. I predominantly rely on Intel ICHx on-board controllers with SATA disks, because ICHx works quite well under FreeBSD (especially with AHCI). I personally have no experience with gmirror or gvinum, but I do have experience with ZFS. (I'll have a little more experience with gmirror once I have the time to test some reported problems with gmirror and high interrupt counts when a disk is hot-swapped). > > I hope these are SCSI disks you're showing here, otherwise I'm not sure how > > the > > controller is able to get the primary defect count of a SATA or SAS disk. > > So, > > assuming the numbers shown are accurate, then yes, I don't think there's > > any > > disk-level problem. > > Yes, they are SCSI disks.

This is one of the biggest problems with the majority (but not all) of hardware RAID controllers -- they give you no access to disk-level things like SMART. FreeBSD has support for such (using CAM's pass(4)), but the driver has to support/use it, *and* the card firmware has to support it. At present, Areca, 3Ware, and Promise controllers support such; HighPoint might, but I haven't confirmed it. Adaptec does not. What you showed tells me nothing about SMART, other than the remote possibility its basing some of its decisions on the "general SMART health status", which means jack squat.

Well, the feature I described isn't what's causing your problem, but to clarify: if you change the percentage, it applies immediately.

RE: Large discrepancy in reported disk usage on USR partition
Hi, The space reserved as minfree does not appear to have been changed from the default setting of 8%. Is your suggestion that I should change it to a larger value? I don't understand how modifying it now could fix the situation, but I could be missing something. The output of "tunefs -p /usr" is as follows: #: tunefs -p /usr tunefs: ACLs: (-a) disabled tunefs: MAC multilabel: (-l) disabled tunefs: soft updates: (-n) enabled tunefs: maximum blocks per file in a cylinder group: (-e) 2048 tunefs: average file size: (-f)16384 tunefs: average number of files in a directory: (-s) 64 tunefs: minimum percentage of free space: (-m) 8% tunefs: optimization preference: (-o) time tunefs: volume label: (-L) I have not observed the problem on any of the other ~dozen FreeBSD servers in our data centre. Could the "missing" space be an indication of hardware disk issues i.e. physical blocks marked as bad? Is it possible on UFS2 for disk space to be allocated but hidden somehow? (although I have been running the commands such as "du -x" as superuser) Similarly, is it possible on UFS2 for disk space to be allocated in "lost cluster chains" ?

Large discrepancy in reported disk usage on USR partition
Hi, I have inherited some servers running various releases of FreeBSD and I am having some trouble with the /usr partition on one of these boxen. The problem is that there appears to be far more space used on the USR partition than there are actual files on the partition. The utility "df -h" reports 25GB used (i.e. nearly the whole partition), but "du -x /usr" reports only 7.6GB of files. I have reviewed the FAQ, particularly item 9.24 "The du and df commands show different amounts of disk space available. What is going on?". However, the suggested cause of the discrepancy (large files already unlinked but still held open by active processes), does not appear to be true in this case as problem is present even after rebooting into single user mode. #: uname -a FreeBSD ibisweb4spare.strategicecommerce.com.au 6.1-RELEASE FreeBSD 6.1-RELEASE #0: Sun May 7 04:42:56 UTC 2006 [EMAIL PROTECTED]:/usr/obj/usr/src/sys/SMP i386 #: df -h Filesystem SizeUsed Avail Capacity Mounted on /dev/aacd0s1a 496M163M 293M36%/ devfs 1.0K1.0K 0B 100% /dev /dev/aacd0s1e 496M15M 441M3% /tmp /dev/aacd0s1f28G25G 1.2G96%/usr /dev/aacd0s1d 1.9G429M 1.3G24%/var #: du -x -h /usr 2.0K/usr/.snap 24M/usr/bin 584M/usr/ports 140K/usr/lost+found 7.6G/usr The server is used as a standby machine and a nightly cronjob which uses RSYNC to make a copy of the /usr partition from a live server. Depending on how recently the logs have been culled, the Live server has approximately 7-10GB of data on the /usr partition, so I would expect the same size of data on the standby server. This may be irrelevant, but the server also has an external data directory with 11GB mounted via NFS as a directory under the USR partition. Next, I began to suspect some sort of disk corruption (echoes of the old days of MSDOS lost cluster chains) and I have attempted to find disk issues by running fsck, but no issues were reported and the issue was not remedied. I also tried running fsck in single user mode, again, no improvement. Can anyone suggest what I can try next?

Chuck is right: the "twice as much" is du reporting in the default 512 byte blocks. You probably have the BLOCKSIZE=K set in either ~/.profile or /etc/profile. If you recently upgraded sudo, you should take note that env_reset is now the default. You can return to the old behaviour by adding a line like: Defaults !env_reset to your sudoers file. It might be more secure to not do this with a Defaults line, though. man 5 sudoers for more information. -- -- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

If I remember correctly, the most common reason for this is files that have been deleted, but have not had all references to them closed (i.e. file descriptors). For example, program creates a temporary file, then deletes it but does not _close_ it. This means the filesystem can't free up the used blocks yet. There's no directory entry, so du doesn't see the usage. One way to tell would be to reboot the system. If it comes up with du and df agreeing, then this problem is occurring somewhere. The trickier step may be to figure out what program is causing it. -- Bill Moran http://www.potentialtech.com ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Re: Monitor Disk Usage (Unusual Load Avgs)
Steve, There's the obligatory 'ps -ax' to see what's running. You can also run 'top' to get a constantly updated display of processes. Some other stuff you may want to look around with is 'systat' . Just running the command doesn't show a whole lot but with various options and such you can pull some useful info, check the man page. Something else is 'lsof' which lists open files and such, can help you get an idea of what's open and running. You can also run 'man -k stat' and find lots of other goodies. To find out what DMA mode is running, check your dmesg. 'dmesg | grep DMA' While I can't provide a specific answer to your questions I've pointed out some things that may help you find what you're looking for.

Checking Partition/User disk usage?
This is a pretty simple question, I'm just looking for tools that report back disk or user disk usage. I remember these commands, but I can't remember what they are called Thanks, charlie ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

That sounds like some program keeps one or more files open and writes to it while the directory entry for the file has been removed. (Probably some log file which is kept open, but it might be something else.) Space used by a file is not marked as free until all directory entries referring to the file has been removed AND no program has the file open. This is the normal cause for df/du discrepancies that you describe. -- Erik Trulsson [EMAIL PROTECTED] ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Disk Usage
I have a NFS server running FreeBSD-4.9-RELEASE. It's run fine for several months with five FreeBSD 4.9 systems mounting it's filesystems. Suddenly something started using disk space at the rate of 10 GB/hour on one of the filesystems (which has exported directories). The catch is that a du -k shows a total usage for that file system of much less than df -k. du -k essentially shows the disk usage before the available space started to disappear! Normally I'd presume someone's hiding files under a mount point when I see this but nothings mounted on a directory in this filesystem. Upon reboot the space is not used anymore, df -k and du -k report similar values. Quite simply odd. Some other details... ...this has happened twice in one day, and the rate of "ghost" disk usage is constant and identical in both graphs. The file server is used to serve files to clustered web servers. There's considerable write activity to the NFS server all the time (40-60Mbit/sec) and moderate read access (~10Mbit/sec). Any ideas what would cause the df -k and du -k discrepancy? -- Michael Conlen ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
