Hi All, I''d like to ask about whether there is a method to enforce a certain txg commit frequency on ZFS. I''m doing a large amount of video streaming from a storage pool while also slowly continuously writing a constant volume of data to it (using a normal file descriptor, *not* in O_SYNC). When reading volume goes over a certain threshold (and average pool load over ~50%), ZFS

I recently had an X86 system (running Nexenta Elatte, if that matters -- b101 kernel, I think) suffer hardware failure and refuse to boot. I''ve migrated the disks into a SPARC system (b115) in an attempt to bring the data back online while I see about repairing the former system. However, I''m having some trouble with the import process: hydra# zpool import pool: tank id:

Hello all, I found this dialog on the zfs-devel at zfsonlinux.org list, and I''d like someone to confirm-or-reject the discussed statement. Paraphrasing in my words and understanding: "Labels, including Uberblock rings, are fixed 256KB in size each, of which 128KB is the UB ring. Normally there is 1KB of data in one UB, which gives 128 TXGs to rollback to. When ashift=12 is

Has anyone worked with a x4500/x4540 and know if the internal raid controllers have a bbu? I''m concern that we won''t be able to turn off the write-cache on the internal hds and SSDs to prevent data corruption in case of a power failure. -- This message posted from opensolaris.org

I have historically noticed that in ZFS, when ever there is a heavy writer to a pool via NFS, the reads can held back (basically paused). An example is a RAID10 pool of 6 disks, whereby a directory of files including some large 100+MB in size being written can cause other clients over NFS to pause for seconds (5-30 or so). This on B70 bits. I''ve gotten used to this behavior over NFS, but

I have a ZFS pool that has been corrupted. The pool contains a single device which was actually a file on UFS. The machine was accidentally halted and now the pool is corrupt. There are (of course) no backups and I''ve been asked to recover the pool. The system panics when trying to do anything with the pool. root@:/$ zpool status panic[cpu1]/thread=fffffe8000758c80: assertion failed:

My google-fu is coming up short on this one... I didn''t see that it had been discussed in a while ... What is the status of ZFS support for TRIM? For the pool in general... and... Specifically for the slog and/or cache??? -------------- next part -------------- An HTML attachment was scrubbed... URL:

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.

Hello all, I have an oi_148a PC with a single root disk, and since recently it fails to boot - hangs after the copyright message whenever I use any of my GRUB menu options. Booting with an oi_148a LiveUSB I had around since installation, I ran some zdb traversals over the rpool and zpool import attempts. The imports fail by running the kernel out of RAM (as recently discussed in the list with

Also rework things so that if someone were to add an opcode without adjusting the values in these arrays, there will be a compilation error.

After multiple power outages caused by storms coming through, I can no longer access /dev/zvol/dsk/poolname, which are hold l2arc and slog devices in another pool I don''t think this is related, since I the pools are ofline pending access to the volumes.

Hi, all, I think I''m missing a concept with import and export. I''m working on installing a Nexenta b134 system under Xen, and I have to run the installer under hvm mode, then I''m trying to get it back up under pv mode. In that process the controller names change, and that''s where I''m getting tripped up. I do a successful install, then I boot OK,

We are currently experiencing a very huge perfomance drop on our zfs storage server. We have 2 pools, pool 1 stor is a raidz out of 7 iscsi nodes, home is a local mirror pool. Recently we had some issues with one of the storagenodes, because of that the pool was degraded. Since we did not succeed in bringing this storagenode back online (on zfs level) we upgraded our nashead from opensolaris b57

Hi, more than a year ago I created a mirrored ZFS-Pool consiting of 2x1TB HDDs using the OSX 10.5 ZFS Kernel Extension (Zpool Version 8, ZFS Version 2). Everything went fine and I used the pool to store personal stuff on it, like lots of photos and music. (So getting the data back is not time critical, but still important to me.) Later, since the development of the ZFS extension was
