Hi, I just had my Dell R610 reboot with a kernel panic when I threw a couple of zfs clone commands in the terminal at it. Now, after the system had rebooted zfs will not import my pool anylonger and instead the kernel will panic again. I have had the same symptom on my other host, for which this one is basically the backup, so this one is my last line if defense. I tried to run zdb -e

After several days of trying to get a 1.5TB drive to resilver and it continually restarting, I eliminated all of the snapshot-taking facilities which were enabled and 2009-10-29.14:58:41 [internal pool scrub done txg:567780] complete=0 2009-10-29.14:58:41 [internal pool scrub txg:567780] func=1 mintxg=3 maxtxg=567354 2009-10-29.16:52:53 [internal pool scrub done txg:567999] complete=0

I''ve noticed that fstyp on a floppy media formatted with "pcfs" now needs somewhere between 30 - 100 seconds to find out that the floppy media is formatted with "pcfs". E.g. on sparc snv_48, I currently observe this: % time fstyp /vol/dev/rdiskette0/nomedia pcfs 0.01u 0.10s 1:38.84 0.1% zfs''s /usr/lib/fs/zfs/fstyp.so.1 seems to add about 40 seconds to that

Not sure what the best list to send this to is right now, so I have selected a few, apologies in advance. A couple questions. First I have a physical host (call him bob) that was just installed with b134 a few days ago. I upgraded to b145 using the instructions on the Illumos wiki yesterday. The pool has been upgraded (27) and the zfs file systems have been upgraded (5). chris at bob:~# zpool

The "icat" name comes from the employed command line tool which might be replaced at any time with a different implementation. The command name is a bit confusing because it's similar to "cat" but act as "donwload". download_inode is more clear and descriptive.

Short question: I''m curious as to how ZFS manages space (free and used) and how its usage interacts with thin provisioning provided by HDS arrays. Is there any effort to minimize the number of provisioned disk blocks that get writes so as to not negate any space benefits that thin provisioning may give? Background & more detailed questions: In Jeff Bonwick''s blog[1], he

I made a bad judgment and now my raidz pool is corrupted. I have a raidz pool running on Opensolaris b85. I wanted to try out freenas 0.7 and tried to add my pool to freenas. After adding the zfs disk, vdev and pool. I decided to back out and went back to opensolaris. Now my raidz pool will not mount and got the following errors. Hope someone expert can help me recover from this error.

Hi all, - There is a worth thing to note about these changes, which is the handling of $ATTRIBUTE_LIST attribute, that is rare attribute. When there are a lot of attributes and there is no more space in the MFT record, all those attributes that can be made non-resident are moved out the MFT, so this is where the $ATTRIBUTE_LIST comes in. - Most people must have seen the ugly "EDD

Test is based on file signature, it checks whether the extracted file is the $MFT.

I was wondering if it''s planned to give some control over the metaslab allocation into the hands of the user. What I have in mind is an attribute on a ZFS filesystem that acts as modifier to the allocator. Scenarios for this would be directly controlling performance characteristics, e.g. having system and application files being allocated on the inner side of the platter while pushing

The `lofiadm'' man page describes how to export a file as a block device and then use `mkfs -F pcfs'' to create a FAT filesystem on it. Can''t I do the same thing by first creating a zvol and then creating a FAT filesystem on it? Nothing I''ve tried seems to work. Isn''t the zvol just another block device? -- -Gary Mills- -Unix Group-

OK, I am a butt-head and accidentally destroyed my last snapshot of a replicated ZFS dataset. The dataset is NOT mounted and other than a resilver going on, there is no I/O going on to this dataset. Is there any way to roll back and get my latest snapshot back? from zpool history -i: 2012-06-18.10:34:00 zfs destroy xxx at 1339668001 2012-06-18.10:34:00 [internal destroy txg:2213852] dataset =

I have a huge problem with ZFS pool fragmentation. I started investigating problem about 2 weeks ago http://www.opensolaris.org/jive/thread.jspa?threadID=34423&tstart=0 I found workaround for now - changing recordsize - but I want better solution. The best solution would be a defragmentator tool, but I can see that it is not easy. When ZFS pool is fragmented then: 1. spa_sync function is
