Hello,

When I tried to mount /appli21 with smit, the terminal "freezed" (ssh connection still active but always showing the same window, no new telnel or ssh connection allowed) and I had to have the machine restarted to be able to connect again.

my volum group datavg:

my fsck (made after the crash)
The current volume is: /dev/lvappli21
Primary superblock is valid.
J2_LOGREDO:log redo processing for /dev/lvappli21
Primary superblock is valid.
*** Phase 1 - Initial inode scan
*** Phase 2 - Process remaining directories
*** Phase 3 - Process remaining files
*** Phase 4 - Check and repair inode allocation map
*** Phase 5 - Check and repair block allocation map
File system is clean.

I don't know why the OS crash and I am quite afraid to try again to mount the filesystem as I do not want it to go down again.
Can anyone give me a track?

thanks
