rm hanging

GBR — Thu, 18 Oct 2007 10:10:48 GMT

Hello,

I was in the middle of transferring a file from a Windows box to an HP-UX server (via ftp) when I decided to cancel the ftp from the windows machine. I then logged onto the HP-UX server to delete the partially transmitted file, but the rm command just hangs. Does anyone have an idea of how this can be resolved?

Shalom,

You need to terminate the ftpd process associated with the file before you can delelte the file. Its got an open file handle and is causing the hang.

If you kill the ftpd process or better yet, stop the ftp process on the windows box, this situation will be resolved.

Hi:

You most certainly can remove (delete) open files. The space allocated to the file is simply not removed until its link count reaches zero.

I would ask, instead, if you are dealing with an NFS mount that has gone stale. Another symptom of such a stale handle would be an unresponsive 'ls' and/or 'bdf'.

1. bdf is responding well, and so is ls.
2. I tried kill and kill -9 on the ftpd process that was transferring the file and still nothing. The rm is still hanging.
3. The windows process was terminated as well, or at least I think it was. I killed the ftp client that was making the transfer.

Hi,

what does fuser says?
'll' (long-list) in the directory works?

1. ll works in the directory where the file resides.
2. fuser returns:
: 2943o

rm is still hung.

Hi (again):

Let's make sure you are running what you think you should be. What do this return?

# whence -v rm
# whence -p rm

In fact, try using the absolute path:

# /usr/bin/rm file_to_remove

Regards!

Hi,

have you checked your syslog for a possible disk problem?
It sounds as if the rm command is waiting for an answer - which it apparently does not get - from a disk.

Yup, I have some disk issues. I checked my syslog and ran a dmesg. I'm recieving async read errors.

What's the best way to check for disk corruption? Would it be the dd command?
