Subject: about faulty spare-disk interrupts synchronization
Date: Wed, 23 Dec 2009 19:51:33 +0800 [thread overview]
Message-ID: <200912231951301400282@gmail.com> (raw)
Hi,
Is it intended that when a spare disk status gets faulty (detached from raid or really faulty)
synchronization is interrupted ? We found that case several days ago with kernel version of 2.6.24,
after we unplugged a spare disk of a raid5 which had bitmap and was recovering, the spare disk
status became faulty and synchronization restarted from 0%.
Looking into the md code, i find that in md/md.c/md_error(), it doesn't make a difference between
spare disks and normal disks. Should we make a faulty spare disk not interrupt raid synchronization ?
Disks nowadays have become much larger, and recovering one disk may cost several hours or even longer.
