thanks Carlos,

this confirms my suspicions... xfs it is then!

Wannes:

There is a current issue with EXT4, the Linux Kernel and Gluster. It is a long story, but, in the end there is a bug there that won't be addressed any time soon.

If at all possible, like gluster's/ RH's documentation recommends, use XFS and make sure you prepare the partition with -i size=512.

At least then you are fully compliant.

Hello Joe,

 

Could it be that gluster has issues with the 64 bit ext4 filesystem? As a test I’m moving one of the volumes to an xfs volume… I hope I’ll be able to answer that question myself soon.

This tells us that there is a chunk of hash map missing. My guess would be that the server you're nfs mounting from cannot connect to one of the bricks.

Hello all,

 

I’ve already tried to post this, but i’m unsure it arrived to the mailing list.

 

I have some issues regarding my nfs mounts. My setup is as follows:

Rhel 6.4, gluster 3.4.2-1 running on a vm (4 cores, 8GB ram) attached to a san. I have one disk on which are all the bricks (formatted ext4 in 64 bit mode) of 25TB.

On the gluster side of things, everything works without issues. The trouble starts when I mount a volume as an nfs mount.

Lots of volumes work without issues, but others behave strangely. The volumes that act weird generally contain many files (can be accidental?).

The volumes in question mount without issues, but when I try to go into any subdirectory sometimes it works, sometimes I get errors.

 

On windows with nfs client: access denied

The weirdest thing is it changes from time to time which files and directories work and which don’t

Any ideas?

 

Thanks!
