[Ocfs2-users] OCFS2 strage freezes

[Yuri Kirsanov]

Good day, everyone.

I have SAN server build with Openfiler OS, with iSCSI mode turned on. I have 
two nodes, which connect to that server via iSCSI, using one of two active 
iSCSI partitions. I've installed ocfs2 1.3.3 with kernel 2.6.23.1, configured 
it, made ocfs2 partition and was successful in mounting it on both nodes. 
Everything works just fine, I can upload file from one node and delete it 
using another one, except for one strange thing. When I'm using ocfs2 mounted 
partition from one node, for example, uploading 1Gb test file into it, and I 
try to access that partition from another node - just to read directory, for 
example, - both nodes "freeze" for about 15-20 seconds, both operations just 
stops for a while, and then copying continues on first node, while second one 
gets directory listing.

I have no errors on both nodes, neither iSCSI ones, no ocfs2. All three 
servers are joined together using 1Gbit/sec network switch and there's no 
other machines on that switch.

If you need any information, please feel free to ask me about it. Thanks in 
advance!
