| |
Are there any remaining issues with file locking over NFS in the 2.2.x kernels ? I am aware of the server issues but not any client ones.
Here is a simple case using the program 'inc' (which includes new mail - part of nmh-0.27 as comes with RedHat 6.0). It is compiled for fcntl locking.
NFS Server - Irix 6.4 NFS v2/v3 capable NFS Client - RedHat 6.0 Linux
Kernel Status ------ ------ 2.0.36 works
2.2.5-22 inc: unable to lock and fopen /nfs/home/test/.mail kernel: lockd: failed to monitor xx.xx.xx.xx 2.2.10 ditto 2.2.16 ditto
2.3.16 works ------ ------
strace says..
open("/nfs/home/test/.mail", O_RDWR|O_NONBLOCK) = 3 fcntl(3, F_SETLK, {type=F_WRLCK, whence=SEEK_SET, start=0, len=0}) = -1 ENOLCK (No locks available) close(3) = 0
I didn't want to waste any time on this if it was a known problem or my silliness. It would be great if all the NFS v2 issues could be resolved for 2.4 ...
