mhddfs mount in /etc/fstab fails if periodic fsck kicks in... how to solve?

Question

( ubuntu oneiric 11.10 server)

Here is my /etc/fstab

# /etc/fstab: static file system information.
proc            /proc           proc    nodev,noexec,nosuid 0       0

If the periodic fsck run starts during boot, my mhddfs mount fails and the server waits for a ctrl+d to continue boot...

How can I prevent the "hang" while keeping my periodic fsck runs ?

Answer 1

When you look at the sixth field in your /etc/fstab, you see there a 0. This means the mhddfs is not automatically fscked. So one workaround of your problem is to add noauto to your fstab:

mhddfs#/storage/HDD/SAM-2000-1/Medias,/storage/HDD/SAM-1500-1/Medias,/storage/HDD/SEA-1000-1/Medias,/storage/HDD/SEA-1000-2/Medias /storage/BigData/Medias fuse defaults,allow_other,nofail,noauto 0 0

So the filesystem will not automatically mounted at startup. Furthermore you write a script which basically mounts your mhddfs and add it at some late point in the boot process.

This makes sure that the fsck runs normal. If your system tries to mount the mhddfs, all other fscks are finished and your system should boot normal.
