            sorry, it's not quite enough information..
            it would be very helpful if you can start the test and then grab logs (let's start with messages and/or consoles) from all the nodes.
            one interesting thing from the log attached:

            there are 2 kinds of mds fault injections, I think when the crash happened, it was in the middle of mds_failover
            1. mds1 failover
            reboot mds1
            mount the disks to failover pair mds2
            after mds1 up, fail back the disks to mds1

            2. mds restart
            this is similar to mds failover, just not mounting the disk to the failover pair but wait and mount the disk back when the server is up

            thanks.. looking at the logs - there were lots of invalidations in OSP which shouldn't be common - regular failover shouldn't cause this.
            can you please explain what the test is doing?

            I just uploaded the lustre log and trace of soak-8, with panic_on_lbug=0. Please let me know if anything else needed.

            sarah I don't think there is any relation here. I think you can either modify the source or set panic_on_lbug=0 in the scripts? or in modules conf file

            Hi Alex,

            I am having a weird issue when setting up the panic_on_lbug=0 permanently on soak-8(MGS), Here is what I did
            1. lctl set_param -P panic_on_lbug=0
            2. umount and remount as ldiskfs and check the config log, and the value was set as 0
            3. mount lustre, check the panic_on_lbug=1, it didn't change.

            I am not sure if this is related to the llog issue here, can you please check? Do you need any log for this? If it is unrelated, I will create a new ticket, and may need delete bad stuff and restart.

            Thanks

            would it be possible to grab full Lustre logs with libcfs_panic_on_lbug=0 ?

            The LBUG seems can be reproduced easily on soak, I have come cross this 2/3 times so far.

            I think this share root cause with LU-13195 - basically llog got corrupted and then lead to different symptoms.
