2.5.62 oops and Raid-5

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,
        sorry to be a pain, but for some reason I
am getting a symoops under 2.5.62, yet everything
works fine in 2.5.58 (although i notice reiserfs
corruption in that one. not good)
 
        The symoops only comes after the raid-5 has
finished rebuilding, or if i try to mount it whilst
its still in degraded mode/rebuilding. either way,
it crashes.
 
md: md0: sync done.
