[zfs-discuss] X4500 device disconnect problem persists
After applying 125205-07 on two X4500 machines running Sol10U4 and removing "set sata:sata_func_enable = 0x5" from /etc/system to re-enable NCQ, I am again observing drive disconnect error messages. This in spite of the patch description which claims multiple fixes in this area: 6587133 repeated DMA command timeouts and device resets on x4500 6538627 x4500 message logs contain multiple device disk resets but nothing logged in FMA 6564956 "Disparity error" for marvell88sx3 was shown during boot-time for example, Has anyone else had any better luck with this? Thanks.

[zfs-discuss] NFS: Cannot share a zfs dataset added to a labeled zone
Is it possible to share a zfs dataset that has been added to a labeled zone? We are running Solaris 10 U4 w/ TX on x86. Currently, we have a zfs file system named zone/restricted. We have a labeled zone named “restricted” loaded to this zfs. The global path is /zone/restricted. We have another zfs file system named zone/data that we want to add as a dataset to the “restricted” zone. The original global path of this zfs file system is /zone/data. The zone path for the zfs dataset after it has been added to the “restricted” zone is /zone/restricted/root/zone/data. We would like to share the data in the zone/data zfs with “restricted” labeled zones on other systems in my network. We have successfully shared a directory created in the “restricted” zone using /zone/restricted/etc/dfs/dfstab, but have been unable to share the zfs dataset /zone/data. We chose to use a zfs dataset instead of just creating a directory in the zone, because it is a large amount of data with new versions released regularly. With each release the zfs can be destroyed and restored from a snapshot containing the new data very quickly. There is an error during boot up of the zone stating the dataset is busy and cannot be mounted. This causes several services to fail and prevents opening a terminal or console window. Is it possible to share a dataset that has been added to a labeled zone? This is a major piece of our configuration and any help with this issue would be greatly appreciated. I know this might sound confusing, so I listed some paths and dfstab file below to help clarify. Thanks [u]zpool[/u] zone [u]zfs file systems[/u] zone/restricted zone/data [u]zone path after dataset added to zone[/u] /zone/restricted/root/zone/data [u]contents of /zone/restricted/etc/dfs/dfstab[/u] share -F nfs -o rw /zone/data This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

It is not clear to me how these timeout/disconnected problems would cause a call to fork() to fail but I can give that a try the next time I need to delete that much data. However, we have disabled NCQ through this mechanism on another system that was locking up ~1/week with several device disconnected messgaes. That system has been up for 2 weeks after disabling NCQ and has not displayed any disconnected messages since then. Can anyone confirm that that 125205-07 has solved these NCQ problems?

So in general,if you can upgrade to more recent bits, then ZFS will happily just tell you what file that is, see: http://blogs.sun.com/erickustarz/entry/damaged_files_and_zpool_status If you cannot upgrade, then see: http://www.opensolaris.org/jive/thread.jspa?messageID=39450&tstart=0 But in your case, you've corrupted a piece of the metadata (object 0xa of the MOS). You can run 'zdb -dv ' to figure out what you've corrupted. For example: fsh-hake# zdb -dv d Dataset mos [META], ID 0, cr_txg 4, 120K, 34 objects Object lvl iblk dblk lsize asize type 0116K16K32K 12.0K DMU dnode 1116K512512 1.50K object directory 2116K512512 0 DSL directory 3116K512512 1.50K DSL props 4116K512512 1.50K DSL directory child map 5116K512512 0 DSL dataset 6116K512512 1.50K DSL dataset snap map 7116K 128K 128K 0 bplist 8116K512512 0 DSL directory 9116K512512 1.50K DSL props 10116K512512 1.50K DSL directory child map 11116K16K16K 4.50K packed nvlist 12116K16K16K 48.0K bplist (Z=uncompressed) 13116K 128K 128K 15.0K SPA history ... Object 0xa would be the " DSL directory child map" object on my pool. As you can guess, corrupting a core piece of metadata is a bad place to be. Your mileage may vary... If you can still access all your data, the best may be to copy the data (or send/recv) to a backup, destroy & re-create the pool. eric ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

[zfs-discuss] data error in dataset 0. what's that?
Hi forum, I did something stupid the other day, managed to connect an external disk that was part of zpool A such that it appeared in zpool B. I realised as soon as I had done zpool status that zpool B should not have been online, but it was. I immediately switched off the machine, booted without that disk connected and destroyed zpool B. I managed to get zpool A back and all of my data appears to be there, but I have a data error which I am unable to track. Apparently it is: DATASET 0, OBJECT a, RANGE lvl=0 blkid=0 I have found this line from output of zdb: Dataset mos [META], ID 0, cr_txg 4, last_txg 1759562, 406M, 362 objects Is anyone able to shed any light on where this error might be and what I might be able to do about it? I do not have a backup of this data so restoring is not an option. Any advice appreciated.
