ls or find command strange

Asep Somantri — Wed, 21 Nov 2007 08:15:05 GMT

If running command "ls -l" of "find" at directory /, server not give a respond (like hang).

But in other direcory, both command are normal.

Why ?

OS is HPUX 11.11 running on rp3440

Greetings,
Most certainly because you may have a NFS mount point and the distant server isnt responding...

Are you running that command as root or as a normal user?

The directory / is located on the root filesystem (/dev/vg00/lvol3), while most other directories are on other, separate filesystems.

The directories /etc and /sbin are also located on the root filesystem. If "ls -l /etc" or "find /sbin" also hang, your root filesystem might be damaged.

Hi,

Yes, I've NFS but so far "bdf" is okay.

But I haven't tried "ls -l /etc".

If root file system corrupted, Do I have to restore from Ignite ? .. or any way that simple without down the machine.

Best Rgds

Hi,

Try using ls -l with different options like

ls -l|head -2
ls -l|tail -2

This will confirm if you have problem retrieving the very old file. Probably that file might be a link file whose reference file is not available.

Thanks,
Srikanth

OK .. then.. what does bdf show?
Do you have mirrored disks?
What do you see when you type vgdisplay -v vg00?
(any stale- are both disks available?)...

My 2 cents

Hi,

First try to identify which FS/NFS is creating the problem.

have you used -xdev option when you run find ....?

Eliminate NFS, by going to the NFS directories and do a ls or ls -lR etc...
see for any errors in syslog or by running dmesg

Also running a find or ls -lR on a heavily used NFS is bound to take time...

If its not NFS then you can continue on which ever FS is causing the problem.
once you have identified a particular FS and if you have proper backups and no other process are using that FS, you can try unmounting it and run fsck on it.

Hi,

Running bdf is OK & there's 1 nfs(linux).
Running "ls -l" & "find " on NFS directory is good.

We have no mirror & "vgdisplay -v vg00" shows no problem at all.

I'm not sure if restart the server will be a good idea.

Rgds,

Hi,

'ls' is working?

For me it sounds like your hard disk is defect.
You can test your hd:
'dd if=/dev/rdsk/ of=/dev/null bs=32768k'
(bs=block-size can be 1024, 2048,... - choose one you want)
you can see in your 'bdf'.
Check that /dev/null exists ;-)

If there's an error or 'in' and 'out' differs, then you've a problem.
Ignite backup is very good, but you'll need a disk which is ok.

Or have you damaged your file sytem with a 'rm *' command?
Compare your 'ls' results with another workstation.

ok - bs=512k or bs=1024k should be enough :-)

You should see something like this for an 'io' disk:
17677440+0 records in
17677440+0 records out

Hi,

I just bought a new server (HPUX 11.31 rp3310) and it also has a problem with the find command. It runs, hang, run, hang... until it finished. dd command doesn't report any problem. The server doesn't have any NFS. How did you solve your problem?

Thanks,
Jason

If you don't have any NFS mounts, this is a different problem. Please create your own thread.

If you think there is connection, you can put a link to this thread.
