Good morning, I have a problem with ZFS: ZFS filesystem version 4 ZFS storage pool version 15 Yesterday my comp with Freebsd 8.2 releng shutdown with ad4 error detached,when I copy a big file... and after reboot in 2 wd green 1tb say me goodbye. One of them die and other with zfs errors: Apr 24 04:53:41 Flash root: ZFS: vdev I/O failure, zpool=zroot path= offset=187921768448 size=512 error=6

Hi Folks.. I have a system that was inadvertently left unmirrored for root. We were able to add a mirror disk, resilver, and fix the corrupted files (nothing very interesting was corrupt, whew), but zpool status -v still shows errors.. Will this self correct when we replace the degraded disk and resilver? Or is there something else that I''m not finding that I need to do to clean up?

Hi matt, I have some problems about understanding zfs COW implemention. Suppose b and c are both children dir of a, if c changes, there will be new versions of both a and c, namely c'' and a''. a a'' b c c'' Because ''..'' in b points to a before this change, shall we modify b to let ''..'' point to a''? If yes,

Hi All, I am looking at trying to understand the conceptual model of how data is grouped and partitioned within a storge pool. In looking at the on disk document that Tabriz sent out a few weeks ago I see that object sets are the grouping which ZFS uses to group objects that are related. Specifially to aid in format and layout of like objects in to a set. So, for example 1 potential object

Followed the instructions here: http://www.freebsd.org/doc/handbook/updating-upgrading-freebsdupdate.html The upgrade borked. Error message: Can't find 'kernel' When I checked with ls /boot/kernel/, the directory does exist. :-( Since the system has encrypted root partion with ZFSonROOT, I tried to follow instructions at https://forums.freebsd.org/viewtopic.php?&t=8958 to boot

For the encryption functionality in the ZFS filesystem we use AES in CCM or GCM mode at the block level to provide confidentiality and authentication. There is also a SHA256 checksum per block (of the ciphertext) that forms a Merkle tree of all the blocks in the pool. Note that I have to store the full IV in the block. A block here is a ZFS block which is any power of two from 512 bytes to

Hi, I was trying to rebuild world on a FreeBSD 10 test system, that I had just installed. ZFS root was setup. I let the installation program do all the ZFS setup and configuration. I put root on a 5 disk encrypted raidz array. Besides the installer configuring 5 times the amount of swap space I asked for (asked for 8gb, installer put 8gb on each drive, for 40gb in total.) everything was working

>Almost certainly your drive is going bad. On Linux I'd tell you to check dmesg for drive errors, I don't know what the FreeBSD equivalent is. But I strongly recommend that you treat that drive as "going to fail any second". I'm not sure that this is the reason. I see the error regardless of the USB disks that I use. And I have a lot of USB disks,10 disks. No,I

I had a sparc64 (Netra X1) running a stable/9 from late March 2013. Actually, the kernel may've been a bit newer than that as I was working with folks to diagnose and repair some Netra-X1 specific issues. But, ZFS worked fine. I have two pools, zroot as a RAID1 (using equally sized partitions at the front of two large disks), and a zdata that is a large pool of the remaining space of both

Yes,I tried cp and I got the same error,that usually happens before rsync,that is able to complete the transfer until 99%. I've detached and reattached the USB disks,but I still see the error.

I know this topic has been discussed many times... but what the hell makes zpool resilvering so slow? I''m running OpenSolaris 2009.06. I have had a large number of problematic disks due to a bad production batch, leading me to resilver quite a few times, progressively replacing each disk as it dies (and now preemptively removing disks.) My complaint is that resilvering ends up

What would you think if I told you that using Windows I no longer had that problem ? Would you still think that there are hardware problems ? And if so, why would they only manifest themselves using Linux and FreeBSD and not using Windows?

Mario, Are you running windows on the same hardware as Linux/BSD ? Is it a dual-boot system? If you have different systems for windows vslinux, it's possible there is a HW issue with one of them.

Hello All I read this thread Resilver/scrub times? for a few minutes and I have recognize that I dont know the different between Resilvering and Scrubing. Shame on me. :-( I dont find some declarations in the man-pages and I know the command to start scrubing "zpool scrub tank" but what is the command to start resilver and what is the different? -- Best Regards Alexander Dezember, 20

I have a situation where my zpool (with two radiz2s) is resilvering and reaches a certain point, then starts over. There no read, write or checksum errors. The disks do have a fair amount of resilvering to do, as I''ve had a variety of disk failures. But at the core of things, there''s enough parity data to avoid data loss, and the zpool is functioning fine, albeit in a
