Re: NFS file transfer limitation

Hi friends,
Any one please guide me, what i supposed to do to overcome this issue.
I checked file size limitation by executing the command ulimit.

 

ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 0
file size               (blocks, -f) 102400000
pending signals                 (-i) 14288
max locked memory       (kbytes, -l) 32
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 0
stack size              (kbytes, -s) 10240
cpu time               (seconds, -t) unlimited
max user processes              (-u) 14288
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

 It showed that allowable file size is 100GB approximately.

Are you talking about the 66 GB free space here, after it aborts as being full?

This is a linux sysadmin question, not HP-UX.  Perhaps you have quotas?

Or thin provisioning on a 3PAR?  :-)

This would give a different error, a signal SIGXFSZ.

Re: NFS file transfer limitation

As Dennis mentioned, this is a Linux issue so this thread will likely be moved to a different forum by one of the moderators.

 

That said, now that you know you are looking at a Linux issue where the filesystem appearing to have plenty of space is reporting no space you may want to do some Google searches for that condition.  The first couple searches I tried showed things like checking whether you are running out of inodes (df -i) or it could be that some large files were deleted from the filesystem but some process is still holding a reference to those files so the underlying OS has not given back the disk blocks yet.

 

If you have another filesystem on the same system with sufficient space I would suggest trying the operation in a different filesystem.  You could also try rebooting the Linux system to eliminate the possibility of a rogue process holding file system space hostage for files that have been deleted.

Except df(1) thinks there is space.  I would think that even if Linux is "better" than UNIX, it wouldn't try improving on the concept of what's free.

Of course you need to run df(1) at the same time as the error.

lsof could be used to find those proceses and save you a reboot.
