Hi,
When I use the nfs at RHEL with kernel-2.6.31 and nfs-utils-1.2.0,
I got a problem, but i don't sure.
The process:
Step1: [22:40:9] Open file /mnt/nfs/file(OK)
Step2: [22:40:9] Lock file
[22:40:9] Lock file success
Step3: [22:40:9] Reboot the nfs server
If reboot success, put <enter> to continue
Step4: [22:42:16] Write data to file
[22:42:16] Write data success
Step5: [22:42:16] Unlock file
[22:46:30] Unlock file success.
Step6: [22:46:30] Close file /mnt/nfs/file
[22:46:30] Close fiel /mnt/nfs/file success
The problem is at step5, unlock file takes 4 min, it's a long time than expected.
When traceing the kernel, I find SUNRPC call call_connect timeout many times,
one timeout is 1min.
I think it's a problem of kernel, but i don't know why, can someone help me ?
thanks,
Mi Jinlong
