Sorry if this is not the appropriate place to ask -- I would
appreciate if you would direct me to the right site :-)
Since a few days, we get lots of messages like
Mar 19 15:45:12 server kernel: raid0_map bug: hash->zone0==NULL for block 1895815569
Mar 19 15:45:12 server kernel: Bad md_map in ll_rw_block
Mar 19 15:45:12 server kernel: raid0_map bug: hash->zone0==NULL for block 1895815569
Mar 19 15:45:12 server kernel: Bad md_map in ll_rw_block
Mar 19 15:45:15 server kernel: raid0_map bug: hash->zone0==NULL for block 1895815569
in our syslogs. We have RedHat 6.0 with kernel 2.11 and the
raid-patches for that kernel. /proc/mdstat contains
Personalities : [raid0] [translucent]
read_ahead 1024 sectors
md0 : active raid0 sdc1[1] sdb1[0] 17847936 blocks 16k chunks
unused devices: <none>
and our raidtab is
raiddev /dev/md0
raid-level 0
persistent-superblock 1
nr-raid-disks 2
nr-spare-disks 0
chunk-size 16
device /dev/sdb1
raid-disk 0
device /dev/sdc1
raid-disk 1
Do we have to fear something really weird? What are youre suggestions?
I would like to reconstruct the raid, but I have to install a backup
server, first ...
BTW, should we stay with kernel 2.2.11, or should we upgrade to 2.14
and the raid patches at http://people.redhat.com/mingo/?
Many thanks for your attention!
Regards,
Ulf
P.S.: Please CC: me, I'm not on this list at the moment!
