[zfs-discuss] Kernel panic on zpool status -v (build 143)
Hello, I got a zfs panic on build 143 (installed with onu) in the following unusual situation: 1) 'zpool scrub' found a corrupted snapshot on which two BEs were based. 2) I removed the first dependency with 'zfs promote'. 3) I removed the second dependency with 'zfs -pv send ... | zfs -v receive ...' 4) 'zfs destroy' said dataset busy when called on the old snapshot. So I rebooted. 5) After the reboot, the corrupted snapshot could be successfully destroyed. 6) One dataset and two other snapshots created on the way (in (3)) were removed. 7) Now 'zpool status -v' *crashed* the kernel. 8) After a reboot, 'zpool status -v' caused a crash again. I ran 'zpool scrub' and will report what happens once it's finished. (It will take pretty long.) An mdb session output is attached to this message. I can provide the full crash dump if you wish. (As for the ::stack at the end, I'm not sure if it's meaningful. This is (unfortunately) not a debugging kernel, so the first 6 arguments should not be stored on the stack.)

Re: [zfs-discuss] Trouble detecting Seagate LP 2TB drives
It's an N280, which doesn't support 64-bit at all. I have a second system that has an Atom 330, which is detected as 64-bit without any extra settings.

[zfs-discuss] Resilvering onto a spare - degraded because of read and cksum errors
Hi, I awoke this morning to a panic'd opensolaris zfs box. I rebooted it and confirmed it would panic each time it tried to import the 'tank' pool. Once I disconnected half of one of the mirrored disks, the box booted cleanly and the pool imported without a panic. Because this box has a hot spare, it began resilvering automatically. This is the first time I've resilvered to a hot spare, so I'm not sure whether the output below [1] is normal. In particular, I think it's odd that the spare has an equal number of read and cksum errors. Is this normal? Is my spare a piece of junk, just like the disk it replaced? [1] r...@weyl:~# zpool status tank pool: tank state: DEGRADED status: One or more devices could not be opened.

I was just pointing out the fallacy of thinking that Nexenta might work on hardware that OpenSolaris doesn't (or has problems with). Actually, the kernel in Nexenta is not truly identical, and generally leads official OpenSolaris releases. (We're using a 134 kernel at present, plus a bunch of individual fixes and some of our own additions.) So while you might think that if something doesn't work in OpenSolaris it won't work in Nexenta, you might be surprised. (Then again, you might not!) Trying certainly wouldn't hurt. - Garrett ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
