How to check mounted filesystem

[SKSingh_1]

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 Sep 14 2007 dmdata14
$ bdf sks.test

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

Hi SKS

File system repair you can use fsck command

#fsck /dev/vg/lv

[Sajjad Sahir]

what type of file system it is
fstyp /dev/vg03/logicalvolme
give me out put

sajjad

[SKSingh_1]

#fsck -F vxfs -o full,nolog /dev/vg00/lvol3
vxfs fsck: /dev/vg00/lvol3 is currently mounted
#fsck -F vxfs -o full,nolog /dev/vg00/rlvol3
vxfs fsck: /dev/vg00/rlvol3 is currently mounted
#

[Sajjad Sahir]

fsck never work on mounted file system
u have ot umount it

sajjad

[Sajjad Sahir]

Dear

u have to umount
umount /umountpoint

then do fsck
ok

[SKSingh_1]

You know this is root FS....can't Unmount!!
any solution without reboot?

[SKSingh_1]

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
#

[Jeeshan]

Hi again

did you try the command

#fsck -o full /dev/vg/lvol

[Jeeshan]

Hi again

#fsck -o full /dev/vg/lvol

[Sajjad Sahir]

dear pls give me out put of this
i have to confirm it which type of file ystem it is

pls revert back soon

sajjad

[Sajjad Sahir]

dear Sikh sorry there is mistake i have written above fstyp no need to use that one
I think i typed wrongly. if u root file sytem is corrupted, u have to boot in single usermod and do fsck i don't know any other option

thanks and regards

sajjad

[Sajjad Sahir]

dear brohter you have Online-JFS?

sajjad

[SKSingh_1]

yes I have online JFS. fstype is vxfs.

[SKSingh_1]

Hi ahsan,

same error.

#fsck -o full /dev/vg00/lvol3
vxfs fsck: /dev/vg00/lvol3 is currently mounted
#

[Sajjad Sahir]

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

sajjad

[Sajjad Sahir]

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

How much space is in sks.test/dmdata? Do you care if you lose the space and/or the files?

If you can't unmount the file system and you don't want to shut the system down, you can just use a hammer on that directory and delete it:
# /sbin/unlink sks.test/dmdata

Make sure you read the WARNINGS on unlink(1m).

[Rasheed Tamton]

Hi,

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

Is this /sks.test/dmdata a local file system or NFS mounted, etc.

Can you post the output of the below:

fuser -u /sks.test/dmdata

find /sks.test|grep dmdata
bdf /sks.test/dmdata
cd /sks.test/dmdata
ll
bdf .


If you do not use unlink as above and if you are sure that you do not want the data, try doing a rm from inside the dir and you must have the correct permissions for doing that - no ACL ,etc.

cd /sks.test/dmdata
pwd
rm -rf * (make sure you are inside the /sks.test/dmdata dir, before you do a rm -rf)

or
cd /sks.test
pwd
rm -rf dmdata

Did you check the syslog.log for any disk related errors, etc.

Let us see the result.

Rgds.

I have given details that this is on / filesystem. Its a empty directory with filesystem I/O error and causing backup to fail.

Atlast server rebooted and problem fixed.
Thanks everyone for help.

[SKSingh_1]
