I have a FreeBSD 6.2-based server running a 1.2TB graid3 volume, which consists of 5x 320gb SATA hard drives. I've been getting errors in /var/log/messages from the graid3 volume, which I suspect means an underlying fault with one of the disks, but is there any way to decipher which one of these drives is throwing errors? I've checked smartc...

Hello list, Last night one disk of my desktop machine dead causing a hard lock of the computer. It was a component of a mirror volume so it wasn't as serious as it initially looked. Unfortunately, the metadata structure of my data partition (a geom raid3 array with tree components ) seems to be corrupted by this hard lock, the following message is scrolled constantly on the screen: GEOM_RAID3: Device datos created (id=3217021940). GEOM_RAID3: Device datos: provider ad6s2 detected. GEOM_RAID3: Device datos: provider ad5s2 detected. GEOM_RAID3: De...

Hi. Here you can find patches with changes to gmirror(8) and graid3(8): http://people.freebsd.org/~pjd/patches/gmirror.7.patch http://people.freebsd.org/~pjd/patches/graid3.patch The patches does the following: - Significant synchronization speed improvement. Now many parallel synchronization I/O requests can be used instead of only one before. Many people...

...ork, because graphic files are big and should open fast. Not as fast as local ones, I understand that, but speeds about 12-15Mb/s is not enough for sure :) Only problem I see: which software RAID5 solution should I prefer? FreeBSD-based, of course! I see these variants: (1) FreeBSD 6(7?) + graid3. Slow, one disk for checksums is bottleneck, as far as I understand. (2) FreeBSD 6(7?) + gvinum/radi5. Is it stable enough?! Is it complete? when I try it about 6 months ago in VMWare installation with 5 virtual disks, I got panics and strange behaviour after "crashing"...

We have been struggling with our Lustre performance for some time now especially with large directories. I recently did some informal benchmarking (on a live system so I know results are not scientifically valid) and noticed a huge drop in performance of reads(stat operations) past 20k files in a single directory. I''m using bonnie++, disabling IO testing (-s 0) and just creating, reading,

Hi all, I have a 5 drive RAIDZ volume with data that I''d like to recover. The long story runs roughly: 1) The volume was running fine under FreeBSD on motherboard SATA controllers. 2) Two drives were moved to a HP P411 SAS/SATA controller 3) I *think* the HP controllers wrote some volume information to the end of each disk (hence no more ZFS labels 2,3) 4) In its "auto

Hi all, I was intending on trying out gjournal on a new disk i've added in my desktop. I had a look to see what the most recent patch provided by Pawel and found http://people.freebsd.org/~pjd/patches/gjournal6_20061024.patch I created the directories as per Pawel's original post (http://lists.freebsd.org/pipermail/freebsd-fs/2006-June/001962.html) and the patch succeeded with no failed

Hey folks, I guess this is an odd question to be asking here, but I could do with some feedback from anybody who''s actually using ZFS in anger. I''m about to go live with ZFS in our company on a new fileserver, but I have some real concerns about whether I can really trust ZFS to keep my data alive if things go wrong. This is a big step for us, we''re a 100% windows
