Hi,
When looping through our ASMLib-configured disks listed in /dev/oracleasm/disks,
taking the minor-major numbers of each of them to look up the devices in /proc/partitions,
we've noticed references to /dev/dm-XX devices sometimes differ (for ex; you'll find for
say, disk DATA_002 a reference to /dev/sdp1 on node 1 of cluster whereas this DATA_002
will refer to /dev/sdb1 on node2).
Two questions:
1/ Should minor-major numbers output be the same when querying ASMLib disks with
"oracleasm querydisk -d <disk>" command executed on each node of a cluster ?
(should we find exact same "Disk <disk> is a valid ASM disk on device [min,maj]" message on both nodes ??)
2/ Whether the above is true or not, same question for devices referenced in /dev... ? (should my
DATA_002 display the same "/dev/dm-14" for ex. on both sides of our cluster... ?)
Tried to find doc about that but to no avail.
Thanks a lot.
Regards,
Sebino
