filesystem issues

amipankaj — Thu, 30 Oct 2008 08:27:51 GMT

hi experts,

i had created filesystem yesterday and mouted it. each filesystem was created of size 35gigs but now its showing only of 6gigs when i see with bdf mount point, but if i use bdf with their lv then it give me the actual size.

i tried to use fsadm but its giving me following error.

fsadm -b 36700160m /oracle/DEY/sapdata1
fsadm: /etc/default/fs is used for determining the file system type
UX:vxfs fsadm: ERROR: V-3-20279: /oracle/DEY/sapdata1 is not the root inode of a vxfs file system

even i tried to umount it but its also giving the below error.

umount /oracle/DEY/sapdata1
umount: cannot unmount /oracle/DEY/sapdata1 : Block device required
umount: return error 1.

please help.

thanks in advance.

Hi,

I suspect that the filesystem you created yesterday is not currently mounted.
When you do a bdf is the displayed filesystem name same as that you are mentioning in bdf.
e.g.
bdf /oracle/DEY/sapdata1
should return something like
Filesystem kbytes used avail %used Mounted on
/dev/vgxx/lvolyy
524288 285296 237456 55% /oracle/DEY/sapdata1

This is just an example - ignore the names and values.

I think when you do a bdf, the output you are seeing is filesystem beneath which you have another directory /oracle/DEY/sapdata1 which is mount point for your new filesystem.

Please post the output of
bdf /oracle/DEY/sapdata1

also post the output of

bdf | grep "The lvol name you created yesterday"

Ninad

Hi Ninad,

thanks for reply but i have already mounted it...please below output.

mount /dev/vgdey_o2/lv_sd1 /oracle/DEY/sapdata1
mount: /dev/vgdey_o2/lv_sd1 is already mounted on /oracle/DEY/sapdata1

bdf /oracle/DEY/sapdata1

Ninad_1 — Thu, 30 Oct 2008 08:46:37 GMT

Hi,

ok.
Can you also let us know if either /oracle/DEY or /oracle is another filesystem.
Please post the outputs of
bdf /oracle/DEY
and
bdf /oracle

One more possiblity is that you mounted
/oracle/DEY/sapdata1 first and then mounted
/oracle OR /oracle/DEY (whichever may be the filesystem)

In such a case - if no applications are using the filesystem /oracle/DEY/sapdata1 currently - then you can try unmounting and then mounting it again.

Ninad

hi Ninad,

here is the problem ....

bdf /oracle/DEY
Filesystem kbytes used avail %used Mounted on
/dev/vgdey_o2/lv_sd1
6291456 21352 6221120 0% /oracle/DEY/sapdata1

Filesystem kbytes used avail %used Mounted on
/dev/vgdey_o2/lv_sd1
6291456 21352 6221120 0% /oracle/DEY/sapdata1

both of the mountpoints are mounted on the same lv....and also the the mountpoint .oracle.dey is mounted on another lv
/dev/vgdey_o1/lv_oracle
6291456 21352 6221120 0% /oracle/DEY

please let know what to do....

Ninad,

i have mentioned in my previous post also that i am unable to mount the file system, its giving error.

Re: filesystem issues

Ninad_1 — Thu, 30 Oct 2008 09:17:43 GMT

Hi,

Exactly as I suspected.
I think you have mounted /oracle/DEY/sapdata1 first and then mounted /oracle/DEY. Hence it is showing like this. You can confirm this by giving command
mount
This will show at what time each filesystem was mounted.

The resolution as I mentioned earlier is to unmount the filesystems and remount them again.
Then the sequence will be
Check that the applications using the filesystems to be unmounted are stopped first and then

1. umount /oracle/DEY (since you mounted this last)
2. umount /oracle/DEY/sapdata1
3. mount /oracle/DEY
4. Check directory /oracle/DEY/sapdata1 exists (if not create it)
5. mount /oracle/DEY/sapdata1

Regards,
Ninad

Hi Ninad,

here is the exact issue what i got now...

/dev/vgdey_o1/lv_oracle
6291456 21352 6221120 0% /oracle/DEY

the mountpoint /oracle/DEY is mounted on two lv one is ...

/dev/vgdey_o1/lv_sd1.

bdf /oracle/DEY
Filesystem kbytes used avail %used Mounted on
/dev/vgdey_o2/lv_sd1
6291456 21352 6221120 0% /oracle/DEY/sapdata1
and lv_sd1 is llso mounted on mount point /oracle/DEY/sapdata1.

in /etc/fstab we donot have entry for
6291456 21352 6221120 0% /oracle/DEY
and another is /oracle/DEY mounted on /oracle/DEY/sapdata1 .

please let me know how i can recover from here.

thanks in advance.

Hi ,
>>>
fsadm -b 36700160m /oracle/DEY/sapdata1

UX:vxfs fsadm: ERROR: V-3-20279: /oracle/DEY/sapdata1 is not the root inode of a vxfs file system

(i suspected you using worng option in your fsadm)

swlist |grep -i jfs
(do you have ONLINE JFS)..?

please usaully follow this procedure

steps to lvcreate with Online JFS

lvcreate -L

newfs -F vxfs -o largefiles /dev/vg06/rlvolx

mkdir /

cp /etc/fstab /etc/fstab. --> backup your fstab.

vi /etc/fstab

/dev/vgxx/lovlx / vxfs rw,suid,largefiles,delaylog,datainlog 0 2

mount -a

if you have "Online Jfs"

lvcreate -L

fsadm -F vxfs -o largefiles /dev/vgxx/rlvolx

mkdir /

cp /etc/fstab /etc/fstab. --> backup your fstab.

vi /etc/fstab

/dev/vgxx/lovlx / vxfs rw,suid,largefiles,delaylog,datainlog 0 2

mount -a

Re: filesystem issues

Ninad_1 — Thu, 30 Oct 2008 10:06:36 GMT

Hi Roy,

I dont think its something to do with lvol mounted twice - just the way the output of bdf is confusing you.
Have u tried the steps I have told - of umounting anf mounting -
If it is possible - pls try that and check if ur problem is resolved.
Else - I will reply again. am in a meeting now.

Ninad

Ninad_1 — Thu, 30 Oct 2008 10:17:36 GMT

Hi,

ok.
Can you post the output of command mount
The errors are because all the filesystems under /oracle/DEY also need to be unmounted.

Ninad

Johnson Punniyalingam — Thu, 30 Oct 2008 10:18:43 GMT

Hi Roy,

>>we want to recover it....please suggest how....in previous post i have mentioned the problem>>

is it new logical volume created..?

yes

fuser -c /oracle/DEY/sapdata1
(the above command will who currently using the file system)

fuser -ku /oracle/DEY/sapdata1
(kick all the user who currently using)

umount /oracle/DEY/sapdata1

lvremove /dev/vgxx/lvolx

lvcreate -L

newfs -F vxfs -o largefiles /dev/vg06/rlvolx

mkdir /

cp /etc/fstab /etc/fstab. --> backup your fstab.

vi /etc/fstab

/dev/vgxx/lovlx / vxfs rw,suid,largefiles,delaylog,datainlog 0 2

lvdisplay -v /dev/vgxx/lvolxx

mount -a

Thanks,
Johnson

Re: filesystem issues

Johnson Punniyalingam — Thu, 30 Oct 2008 10:22:30 GMT

if this "confirm that bdf - output " doesn't show your correct size

# mv /etc/mnttab /etc/mnttab.bk
# mount -a

(this should create new mnttab)

Thanks,
Johnson

Re: filesystem issues

amipankaj — Thu, 30 Oct 2008 10:31:36 GMT

To mount the filesystems, we have to unmount first, but we are unable to do so...as one Lv is mounted on two mount points and one mount point is mounted one two LV.
