I use "tunefs.lustre --erase-params --writeconf /dev/sda1" to reconfigure the MDT
then the partrition is mounted successfully. However, I got this on the client:
Feb 25 03:28:17 lxslc12b kernel: LustreError: 15c-8: MGC192.168.50.32 at tcp: The configuration from log 'besfs-client' failed (-108). This may be the result of communication errors between this node and the MGS, a bad configuration, or other errors. See the syslog for more information.
Feb 25 03:28:17 lxslc12b kernel: LustreError: 6621:0:(llite_lib.c:1061:ll_fill_super()) Unable to process log: -108
How can I delete the old logs?

主题:[urgent]unable to mount MDT
Dear list,
I got this error when I was trying to mount our MDT, which shares the same partrition with MGS.
[root at mds01 lustre]# mount -t lustre -L besfs-MDT0000 /lustre/besfs/mdt
mount.lustre: mount /dev/sda1 at /lustre/besfs/mdt failed: Invalid argument
This may have multiple causes.
Are the mount options correct?
Check the syslog for more info.

There is nothing in /proc/fs/MGS /proc/fs/MDT, what can I do ?
