[Ocfs2-users] performance of ocfs2 on rhel4

[Federico Renzetti]

I have a separate network 1G eth for cluster  but I really don't know
about storage configuration.

hdparm -t /dev/sdc1 return something like this:

Single node A
/dev/sdc1:
 Timing buffered disk reads:    2 MB in  9.10 seconds = 225.09 kB/sec
 Timing buffered disk reads:  412 MB in  3.01 seconds = 137.04 MB/sec
 Timing buffered disk reads:  322 MB in  3.01 seconds = 106.86 MB/sec

Single node B
/dev/sdc1:
 Timing buffered disk reads:  408 MB in  3.00 seconds = 135.99 MB/sec
 Timing buffered disk reads:  340 MB in  3.01 seconds = 113.05 MB/sec
 Timing buffered disk reads:  404 MB in  3.03 seconds = 133.18 MB/sec

Concurrent node A and B
node A /dev/sdc1:
 Timing buffered disk reads:  108 MB in  9.26 seconds =  11.66 MB/sec
 Timing buffered disk reads:   66 MB in  9.85 seconds =   6.70 MB/sec

node B /dev/sdc1:
 Timing buffered disk reads:    2 MB in  4.39 seconds = 466.28 kB/sec
 Timing buffered disk reads:    2 MB in  5.12 seconds = 400.19 kB/sec

Must I think to ask info to storage admin???
