Dear User23, pboehmer Thanks for the comments and guidance. I will do some further reading on the hardware you suggested.

Good evening After a long hiatus, I am back on the forum. Actually, with my ZFS storage server running without problems for years I only needed to browse every now and then. However, I finally decided to take the leap again and build a proper server (still to be used at home) but with enough...

Re: teTex removed from ports, TeX Live is now the default Te Hi fonz Any luck with this? Otherwise, I could try to install 10.0 now from the latest DVD image and hope that the TeX Live version is on this DVD :q

Re: teTex removed from ports, TeX Live is now the default Te Dear all, Is there an actual migration instruction beyond "Please remove all TeX-related packages based on teTeX" how to actually do this? I cannot do this via portupgrade -a, not even after make deinstall of the respective...

Hi Thanks - I looked now in the source tree and the original source (8.2 with old dates) is still there. I assume I have to delete the source tree and then do the checkout again. regards Malan

Hi I updated my source tree with: svn checkout svn://svn.freebsd.org/base/release/9.1.0 /usr/src After going through the whole updating from source process, I get the following: uname -v FreeBSD 8.2-STABLE #2 r244773M: Fri Dec 28 21:01:33 GST 2012...

Hi It still crashed. I was busy deleting around 109 GB of files, and it crashed with about 25 GB left, and showing 5 GB of RAM free. I am really at my wit's end - despite everything I have tried I am seriously starting to doubt that the ZFS code is as robust as claimed. regards Malan

Hi, I deleted 257 GB of compressed, deduplicated data and it ran out of memory - there was 15 MB free when the system crashed. The value of vfs.zfs.arc_max was around 15 GB (automatic setting). I have 16 GB of memory, now I have set vfs.zfs.arc_max to 12 GB. I will check again once I have...

hi Try bonnie++ -q | bon_csv2html > output.html or bonnie++ -q | bon_csv2txt > output.txt regards Malan

Hi To get an idea of the actual hardware performance of the disk, use diskinfo -c -t -v ada1. You can then compare this performance to the actual performance of your disks using difference file systems (and preferably using a benchmarking program like bonnie++. My read system performance on...

hi traustitj Can you test this with a benchmarking program like bonnie++? I am never too sure about using /dev/zero as a benchmark since it does not represent anything from the real world? regards Malan

Hi The number of disks and the configuration of your array will play a major role (e.g. number of vdevs, number of disks per vdev, physical sector size of the disks, etc.). I learned a lot from reading this thread and this blog. That is the guidance I used in setting up my raid array and...

I recompiled the kernel yesterday, so I have the latest 8.2 RELEASE. This morning I did another 2 deletes (around 50-60 GB each with one from the terminal and one over Samba) and no crash. I checked the RAM usage, Free seems to go down from about 1200 MB to 450 MB during such a big delete...

hi Freddie I have 16 GB RAM, and 40 GB L2ARC. Previously I was worried that it was memory, but it seems to be something else. The delete seems to succeed after running a long time (maybe 10 mins?) during which I monitored the disk activity with gstat. After I recovered the system the...

Hi I had this problem re-occur today. This time I had a monitor and keyboard attached to the server, so I could at least partially observe what happened. I was deleting a directory of around 260 GB from a deduped, compressed volume. The delete seemed to work ok, then I could see the system...

hi My understanding from the ZFS Best Practices Guide is that for ZFS V28 the mirrored or enterprise ZIL's are not a strict requirement any more: Mirroring the log device is recommended. Prior to pool version 19, if you have an unmirrored log device that fails, your whole pool might be lost or...

From my experience, the writing of files with dedup=on is very slow. However, reading the files afterwards are extremely quick (since the same blocks might be cached already). But I cannot think why it should be much better than cloning the same dataset, since you will also be reading the same...

Hi You might have a disk starting to go bad. Have you tried using sysutils/smartmontools to look at the condition of the disk? I had that before a disk packed up totally... regards Malan

hi You can also check http://www.freebsd.org/releases/8.2R/hardware.html for compatibility. regards Malan
