XSAN3.1 / OSX10.9 sloooow write speed
I'm trying to figure out why our XSAN performance is crawled to a halt.
We have an XSAN 3.1 running on OSX 10.9 with 2 MDC controllers and 4 clients (Mac Pro)
The XSAN volume is a raid6 volume of 22TB with a Raid1 2x2Tb for metadata on a 4Gbps Sanbox 5600 fiber switch.
Writespeeds are now almost 0 with BM speedtest utility while readspeed is decent at 230Mb
Volume is pretty full : was 1.8Tb free out of 22Tb capacity and is now 2.62Tb free (of 22Tb cap.)
small manual file copy with drag/drop seems to be OK.
Is this a question of defragmenting the volume ? or should I be looking into something else.
I see no strange mentioning in the loglist.
Tonight I will try this defrag tutorial from Promise Tech unless I find something else.
Any advice is appreciated :-) thx !
