Hi there,
I'm a lil' bit puzzled about this strange scenario:
I've installed XFS 1.2 and EVMS 1.2.0 on a Debian/GNU Linux 3.0 (i386) box
running 2.4.19. I've created a RAID5 storage region from four 9 gig SCSI
drives, upon which I created a container, and inside this region I've created
individual regions which finally make up the logical volumes. I put XFS on
these logical volumes.
After a clean shutdown I will always see messages like the following in
syslog:
kernel: evms: md core: [md0, level=5] raid array is not clean --
starting background reconstruction
This usually took only moments, but after I had added two more SCSI drives
(with IDs below the IDs of the existing drives, in case that matters) the
whole thing became MUCH more time-consuming:
kernel: evms: md core: [md0, level=5] raid array is not clean -- starting
background reconstruction
kernel: evms: md raid5: raid5_run: device sdf operational as raid disk 3
kernel: evms: md raid5: raid5_run: device sde operational as raid disk 2
kernel: evms: md raid5: raid5_run: device sdd operational as raid disk 1
kernel: evms: md raid5: raid5_run: device sdc operational as raid disk 0
kernel: evms: md raid5: raid5_run: raid set md0 not clean; reconstructing
parity
kernel: evms: md raid5: RAID5 conf printout:

Any idea what could be going wrong?!
Thanks,
Ralf
