Re: [zfs-discuss] ZFS problem mirror
So we finnaly got arround the problem, after replacing almost everything it seems that the memory was the devil.

Re: [zfs-discuss] ZFS problem mirror
indeed that's one of the nice things that ZFS is picky on data and allerts you immediatly. Before some files became corrupt and one was wondering what happend and how this was possible since everything seems fine for months :) the more i use solaris the more i love it :) This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] ZFS problem mirror
Hi everyone, i did a nice install of opensolaris and i pulled 2x500 gig sata disk in a zpool mirror. Everything went well and i got it so that my mirror called datatank got shared by using CIFS. I can access it from my macbook and pc. So with this nice setup i started to put my files on but now i notice this : pool: datatank state: DEGRADED status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://www.sun.com/msg/ZFS-8000-8A scrub: scrub in progress for 0h1m, 38.50% done, 0h3m to go config: NAMESTATE READ WRITE CKSUM datatankDEGRADED 0 0 0 mirrorDEGRADED 0 0 0 c5d0DEGRADED 0 0 0 too many errors c7d0DEGRADED 0 0 0 too many errors errors: Permanent errors have been detected in the following files: datatank:<0x3df2> It seems that files are corrupted and when i delete them my pool stay degraded. I did the clear command and then it went ok until after a while i coppied files over from my macbook and again some were corrupted. Iam a affraid to put my produktion files on this server, it doens't seems reliable. What can i do ? anybody any clues. I notice also that i got an error on my boot disk saying (bootdisk is a 20 gig ata): gzip: kernel/misc/qlc/qlc_fw_2400: I/O error Thanks in advance !! best regards, Y This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] ZFS problem mirror
i removed the files that were corrupted,scrubbed the datatank mirror and the did status -v datatank and i got this : pool: datatank state: DEGRADED status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scrub: scrub completed after 0h4m with 0 errors on Tue Jul 8 22:17:26 2008 config: NAMESTATE READ WRITE CKSUM datatankDEGRADED 0 0 4 mirrorDEGRADED 0 0 4 c5d0DEGRADED 0 0 8 too many errors c7d0DEGRADED 0 0 8 too many errors errors: No known data errors then i used the zpool clear command zpool clear datatank : and this it the output : pool: datatank state: ONLINE scrub: scrub completed after 0h4m with 0 errors on Tue Jul 8 22:17:26 2008 config: NAMESTATE READ WRITE CKSUM datatankONLINE 0 0 0 mirrorONLINE 0 0 0 c5d0ONLINE 0 0 0 c7d0ONLINE 0 0 0 errors: No known data errors But is this really ok ? because everytime i got a file corruption i can't do these steps. Btw the files aren't corrupt on my macbook so how come they get corrupted during the transport or on the mirror ? and the error i mentioned on my boot disk is that of some vallue, i searched on the net and found the the package is related with iscsi but i have only sata and ata so.

Re: [zfs-discuss] ZFS problem mirror
Hi running all kinds of tools now even a tool for my hd from WD, so we will she what the results are. I ordered another mobo this morning and if that doesn't work then i will ask a fellow sysop to punt my disk in his solaris array. No i didn't notice anything of kernel panics the only thing i noticed was this line popping up when i did a shutdown The machine himself is just used as a storage array nothing else is running on it, and i use CIFS to share and that works great. gzip: kernel/misc/qlc/qlc_fw_2400: I/O error keep you posted thanks for everything already :) This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
