Description
OST 10 /dev/md30 resident on OSS3
From /var/log/messages
LDisk-fs warning (device md30): ldisk_multi_mount_protect: fsck is running on filesystem
LDisk-fs warning (device md30): ldisk_multi_mount_protect: MMP failure info: <time in unix seconds>, last update node: OSS3, last update device /dev/md30
This is a scenario that keeps sending the customer in circles. They know for certain that an fsck is not running. Since they know that they can try to turn the mmp bit off vi the following commands:
To manually disable MMP, run:
tune2fs -O ^mmp <device>
To manually enable MMP, run:
tune2fs -O mmp <device>
These commands fail saying that valid superblock does not exist, but they can see their valid superblock (with mmp set) by running the following command:
Tune2fs -l /dev/md30
It is their understanding that a fix for this issue was released with a later version of Lustre, but aside from that, is there a way to do this?
