Re: [zfs-discuss] Checksum error: which of my files have failed scrubbing?
Aha, that's the problem. I just upgraded to build 94, and I have alternate boot environments. === > Hmm, I just tried that. Perhaps "No known data errors" means that my files > are OK.

If this is build 94 and you have one or more unmounted filesystems, (such as alternate boot environments), these errors are false positives. There is no actual error; the scrubber misinterpreted the end of an intent log block chain as a checksum error. the bug id is: 6727872 zpool scrub: reports checksum errors for pool with zfs and unplayed ZIL This bug is fixed in build 95. One workaround is to mount the filesystems and then unmount them to apply the intent log changes. - Bill This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Possibly metadata. Since that's however redundant due to ditto blocks (2 or 3 copies depending on importance), it was repaired during the scrub. -- Via iPhone 3G On 05-août-08, at 21:11, soren <[EMAIL PROTECTED]> wrote: >> soren wrote: >>> ZFS has detected that my root filesystem has a >> small number of errors.
