Re: [Moosefs-users] Mfsmount segfaults on autofs

[Stas O. <sta...@gm...>]

More on this - every time running mount -a, I see there are 2 processes:

14630 ?        S<sl   0:00 mfsmount /mnt/mfs -o rw,mfsmaster=master1
14801 pts/0    S<l    0:00 mfsmount /mnt/mfs -o rw,mfsmaster=master1

Then after some time, the 2nd process stops - probably due to below error.

Any idea why mfsmount tries to re-mount itself on every mount -a request?

Thanks.
