Package: dmraid
Version: 1.0.0.rc15-8
Severity: critical
--- Please enter the report below this line. ---
I have a software raid array (raid 0 type), with lvm partitions built over the
raid.
My discs have the following structure:
/dev/sda1 ==> /boot
/dev/sda2 ==> first raid device
/dev/sdb1 ==> unused space
/dev/sdb2 ==> second raid device.
orion:/home/liorc# dmraid -r
/dev/sdb: isw, "isw_cjhfigcfig", GROUP, ok, 488397166 sectors, data@ 0
/dev/sda: isw, "isw_cjhfigcfig", GROUP, ok, 488397166 sectors, data@ 0
(LVM structure attached in the end of the bug report).
With kernel 2.6.26-2, and dmraid 1.0.0.rc13-2, the system boots fine (dmraid
builds the raid array successfully):
[ 89.648985] md0: setting max_sectors to 128, segment boundary to 32767

[ 89.648985] raid0 : nb_zone is 1.
[ 89.648985] raid0 : Allocating 8 bytes for hash.
However, when I upgrade to dmraid 1.0.0.rc15-8, the system fails to boot.
Also, if I don't upgrade dmraid (and still use 1.0.0.rc13-2), but upgrade to
any newer kernel (2.6.29-1, 2.6.29-2, 2.6.30-1), boot fails with the following
error:
Assembling all MD arrays...
mdadm: no devices found for /dev/md0
Failure: failed to assemble all arrays.
Incorrect metadata area header checksum
Volume group "vg0" not found.
I also noticed that 'dmraid -ay' produces the following kernel error:
[ 1711.937067] device-mapper: table: 253:2: striped: Couldn't parse stripe
destination
[ 1711.937072] device-mapper: ioctl: error adding target to table
Please tell me if there is more information I can provide that could be of
help.
Thanks.
Lior.
