Subject: LU-4927 scrub: rebuild stale OST OI mapping
X-Git-Tag: 2.5.59~102
X-Git-Url: https://git.whamcloud.com/?p=fs%2Flustre-release.git;a=commitdiff_plain;h=76031fc50abd3a21395e6f4c09e4d9ab6c60354b;ds=sidebyside

LU-4927 scrub: rebuild stale OST OI mapping

If the osd_oi_lookup() which is called by osd_scrub_check_update()
returns -ESTALE for an OST FID, then it means that the target FID
has invalid OI mapping, and should be rebuilt.
