Public bug reported:
Binary package hint: dmraid
While exchanging a "damaged" Disk (some SMART-values recommended it) i
suffer a strange "bug". Cause of a needed reboot i used the BIOS built-
in functionality to add the new disk to my RAID0. After booting all
works fine (hidden IO from the leading disk to the new disk), except one
thing. "dmraid -s" show me a status named "nosync":
*** Group superset isw_bjcjahbjci
--> Active Subset
name : isw_bjcjahbjci_system
size : 488390912
stride : 128
type : mirror
status : nosync
subsets: 0
devs : 2
spares : 0
After a half hour, the IO disappear and the RAID is in sync (checked it,
with booting from the new disk only attached to the PC) but the status
from the RAID still remains on "nosync". After forcing the raid to
rebuild via dmraid (dmraid -R isw_bjcjahbjci_system) the status jumps
immediately to ok, but the background IO appears again an syncing the
raid again.
Both behaviors are strange. dmraid should report the correct status. If
a raid is rebuilding, it shouldn't reported as "ok" and if the
rebuilding is done it should report as "ok".
No messages regarding dmraid appear in syslog neither in dmesg.
