[zfs-discuss] Checksum error: which of my files have failed scrubbing?

After a scrub a zpool status -v should give you a list of files with unrecoverable errors.

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.

Soren, At this point, I'd like to know what fmdump -eV says about your disk so you can determine whether it should be replaced or not.

One workaround is to mount the filesystems and then unmount them to apply the intent log changes. - Bill ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

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.
