partition disk issue

hi guys,

I've got a strange issue, may be one of you has experienced this.

SunOS 5.10 Generic_118833-33 sun4u sparc SUNW,Sun-Fire-V440

everything is mirrored.

My issue is that I have a umpty directory but seems to have data on. Let me show you

# df -h /data
Filesystem size used avail capacity Mounted on
/dev/md/dsk/d6 19G 6.7G 12G 36% /data

# ls -la
total 22
drwxr-xr-x 4 root root 512 Nov 28 09:25 .
drwxr-xr-x 30 root root 1024 Nov 29 15:41 ..
drwx------ 2 root root 8192 Dec 18 2006 lost+found
drwxrwxrwx 2 root ads 512 Nov 29 15:40 save

# du . -hs
16 ./lost+found
2 ./save
20 .

if some one can help would be so great

Is there another disk or disks mounted to a subdirectory of /data?
If so, umount them, do another ls and du.

I've seen this happen before, where a backup, tar file. etc gets run, before
a disk get mounted. then the disk is mounted, and effectively hides the files, then someone will assume the restore failed, reinstalls the data after the disk has been mounted.

It could be also a file system corruption. Umount it and run fsck, fhinally, mount it again...

Hi guys,

Thanks for your help.

I thought about the fsck and tryied to launch a umount but I cannot it says /data busy. I check cut link on it. relaunch and same error.
I launch a fuser to see is some one is using it. nop nobody.

I'm sorry, but I have to ask you this:
You are umounting "outside" /data, aren't you? Smilie
Now, if the answer is no:
- Check for processes using /data. To achieve this use fuser or lsof (have a look at their man pages for available options).
- Kill those processes.
- Umount again.
- run fsck.

Well yes for sure I have no session insisde /data

I comments sharetab and dfstab which was use for this directory.
I deleted the save link which was at /

Did you use fuser/lsof to see whether some process is working on /data?
