How to check mounted filesystem

SKSingh_1 — Fri, 02 May 2008 17:46:25 GMT

Hi,

I have a directory corrupted.

$ ll sks.test
sks.test/dmdata not found
total 0
drwxr-xr-x 2 root sys 96 Nov 17 2006 dmdata10
drwxr-xr-x 2 root sys 96 Mar 17 2007 dmdata11
drwxr-xr-x 2 root sys 96 Mar 17 2007 dmdata12
drwxr-xr-x 2 root sys 96 Sep 14 2007 dmdata13
drwxr-xr-x 2 root sys 96 Sep 14 2007 dmdata14
$ bdf sks.test
Filesystem kbytes used avail %used Mounted on
/dev/vg00/lvol3 204800 54539 141300 28% /
$
$ uname -a
HP-UX sks01 B.11.00 U 9000/800 661389373 unlimited-user license
$

Do we have any option to check and fix mounted filesystem corruption. I can't reboot server now as its production.

Even removal didn't work.

#rm -r /sks.test
rm: cannot stat /sks.test/dmdata: I/O error
rm: directory /sks.test not removed. Directory not empty

dear friend

I told u u can't do fsck on mounted file system u should umount it first then only u can do fsck, but in u case it is root file system, so that u have to take system in single user mode then do fsck

thanks and regards

Re: How to check mounted filesystem

Sajjad Sahir — Sat, 03 May 2008 04:40:50 GMT

dear friend

u can't take system in single user mode

why u want to remove that directory?

if u want to remove that directory

u can use rm -rf command. ok but remember

it will remove u directory and all contents including subdirectories under that directoires of in it without any warning. so u should careful about use of that command
rm -r never remove only an empty directory
thanks and regards

hi,

Try the following:
Step 1.

$ du -sk /sks.test

Step 2.
Find a directory which resides on a file system other than / and has enough space to contain the directory size as retrived in step 1.

Step .3
Move /sks.test //

post the output of all commands executed above.

revert!
kind regards
