Why does LinuxMCE 0710/0810 mount/umount the Storage partition every 6 seconds?

[Viking]

Hi,

in the sys log i see that my video partition (/dev/md1 three disks RADI5) is mounten and unmounted all the time. Is that normal ?
I have seen this on 0710 and now also on 0810 alpha.

Syslog :

Code:

Hi,

This link looks the same.

Hi,

OK, thanks. Don't see the reason though.

yep, I just learned to live with it too. It's just how lmce works, most of it is caused by UpdateMedia since it is always running and looking for stuff to index.

We have an intricate auto-mounter, with a very short timeout, and when updatemedia does its runs, it triggers the automount again.

I dont mind the constant mounting/unmounting, the annoying part for me is that it makes the kernel log completely useless because of the filesystem messages that get logged each time. I will try to find out if there is a way to suppress those...

Same here.

though I noticed on sunday that the server was really busy mounting/umounting. There was around 50 mount processes when I did an "ps ax|grep mount" and "mount" (without any options) took 10-20 sek. to complete.
So sometimes the system seems to get into trouble. I waited several hours, but it did not really get much better so I rebootet the core and it was gone.
