[Moosefs-users] (no subject)

[Alexander A. <akh...@ri...>]

Hi All !
Please help me to fix a problem.

On one of my mfs-client host I have a strange behavior of mounted FS.

After some time of doing mfsmount
files/directoryes under mounting point becomes unavailable:

# ls /moosefs/mnt/
ls: /moosefs/mnt/: Socket is not connected

# df -h /moosefs/mnt
Filesystem    Size    Used   Avail Capacity  Mounted on
/dev/fuse0      0B      0B      0B   100%    /moosefs/mnt

I am not a really UNIX guru and unfortunately have no idea how to deal with this trouble :-(

In logs I found only this:

Mar 26 16:05:40 myhostname kernel: pid 22997 (mfsmount), uid 0: exited on signal 6

ps really shows no mfsmount process running.

My environment:

# uname -a

Thanks for any help!
