Dear all, this is my first post to this ML. I have a drbd 0.7.22 with 188.8.131.52 kernel on two HP DL380 using cciss. I follow some post to found the best performance and to avoid the freezing of the drbd filesystem without any solution. Follow the best performance parameters that I had found. # drbdsetup /dev/drbd0 show Lower device: 104:09 (cciss/c0d0p9) Meta device: internal Disk options: Local address: 192.168.0.1:7788 Remote address: 192.168.0.2:7788 Wire protocol: B Net options: timeout = 4.0 sec connect-int = 10 sec (default) ping-int = 10 sec (default) max-epoch-size = 16384 max-buffers = 20480 unplug-watermark = 20480 sndbuf-size = 131070 (default) ko-count = 0 (default) Syncer options: rate = 15360 KB/sec group = 0 (default) al-extents = 127 # ./dm -a 0 -b 1M -s 500M -y -m -p -o /win_shares/PERFORMANCE_TEST 4.47 MB/sec (524288000 B / 01:51.733163) During this test if I do a simple 'ls -la' command on a primary node in the drbd filesystem (/win_shares), it left freezed for around 30 seconds and after display the output. The same thing occurs if I copy a lot of files on the drbd partition. Someone has some idea to solve the problem? Thanks Enrico
