[MooseFS-Users] 3.0.39 - linux client, freebsd servers, seems to fail to write data

[Joseph L. <jo...@ge...>]

Hi,

I was testing out moosefs (again) on FreeBSD, when I ran into what appeared to be a performance issue, which I assumed was related to the client.  So, I decided to try a linux client with my FreeBSD master & chunk servers.
All systems are running 3.0.39, the master & chunk servers are on FreeBSD, and the client is Debian (jessie).

I can mount the moosefs share on the client, it shows me existing content.  I can traverse folders, create new folders, ‘touch’ new files, but the second I try and put data into a file, (“echo blah > test.txt” or “dd if=/dev/zero of=test.dd count=1”) the client seems to just lock-up.

It did work with a FreeBSD client, but again, I think there may be a performance issue, as I couldn’t seem to exceed about 140MB/s (SSDs, 10gbit ethernet, many cores, lots of memory) hence why I wanted to try a linux client.  Ultimately I don’t care to run linux clients, but I would have liked to see a comparison in performance between the two.

Any ideas why L linux client doesn’t seem to like my FreeBSD master/chunk servers?
