lsraid reports wrong device list with online RAID5 array

Hi,


I noticed a weird behaviour for lsraid today, that I'm unable to understand yet ... Are the raidtools still maintained, or at least bugs corrected ?


here is what happens, as you can see, my /dev/md2 is composed of /dev/hda3, /dev/hdb3, /dev/hdc3, that are reported right while offline, but /dev/hdc3 is shown as /dev/null while online :-(


[root@ge raidtools-1.00.3]# raidstop /dev/md2

[root@ge raidtools-1.00.3]# ./lsraid -R -p | grep md2 -A 13
# md device [dev 9, 2] /dev/md2 queried offline
# Authoritative device is [dev 22, 3] /dev/hdc3
raiddev /dev/md2
        raid-level              5
        nr-raid-disks           3
        nr-spare-disks          0
        persistent-superblock   1
        chunk-size              128

        device          /dev/hda3
        raid-disk               0
        device          /dev/hdb3
        raid-disk               1
        device          /dev/hdc3
        raid-disk               2

[root@ge raidtools-1.00.3]# raidstart /dev/md2

[root@ge raidtools-1.00.3]# ./lsraid -R -p | grep md2 -A 13
#       /dev/md2
#       /dev/sda
#       /dev/sda1
#       /dev/sda2
#       /dev/sda3
#       /dev/hdc
#       /dev/hdc1
#       /dev/hdc2
#       /dev/hdc3
#       /dev/hda
#       /dev/hda1
#       /dev/hda2
#       /dev/hda3
#       /dev/hdb
--
# md device [dev 9, 2] /dev/md2 queried online
raiddev /dev/md2
        raid-level              5
        nr-raid-disks           3
        nr-spare-disks          0
        persistent-superblock   1
        chunk-size              128

        device          /dev/hda3
        raid-disk               0
        device          /dev/hdb3
        raid-disk               1
        device          /dev/null
        failed-disk             2


Additionnaly, you can see clearly that /dev/hdc3 is not in a failed state:


kalou@ge cat /proc/mdstat | grep -A1 md2 md2 : active raid5 hdc3[2] hdb3[1] hda3[0] 120246272 blocks level 5, 128k chunk, algorithm 0 [3/3] [UUU]
