fsck error: "file system is larger than device"

Daniel_RP — Fri, 10 Nov 2006 03:27:08 GMT

fsck: /etc/default/fs is used for determining the file system type
file system is larger than device
vxfs fsck: cannot initialize aggregate
file system check failure, aborting ...

How Can we solve this problem?

Hi, can you check the vg involved and see if there is a disk missing?

vgdisplay -v vg##

fsck command was executed during the system startup or you run it manually?

Hi,
1.Check dmesg , Syslog , /var/opt/resmon/log/event.log and teh cstm o/p for any hardware issues. also check whether all teh disks are claimed.

2. run bdf and check whether all the filsystems are showing it's actual size.

3. run lvdisplay and check whether the size of that lv and the filesystem size are same, i 've noted in some rare cases this is not the case.

If that is all fine , try the fsck command with an alternate superblock copy which will be available in /etc/sbtab

Thanks,
Siva

carlos ,

What is the bdf showing abt the filsystem size , my assupmtion is it should be different than the lvsize shown in lvdisplay
Show me the bdf o/p for this lv

Re: fsck error: "file system is larger than device"

siva0123 — Fri, 10 Nov 2006 04:06:25 GMT

My calculation from the fstype output shows the filesystem size is approximately 64 GB and the lvdisplay shows the lvsize is approximately 32 GB

Is that correct ?

Re: fsck error: "file system is larger than device"

siva0123 — Fri, 10 Nov 2006 04:11:26 GMT

Carlos,

If that is the case then yo have the follwoing options,
1. Reduce the filesystem size using online jfs

Or
2. Increase the LV size

or

3. Recreate the filesystem and restore using backup.

Hi, Carlos, Can you post the output from bdf /dev/vgHITACHI_P6/lvHIP16?

Please let us know by doing what you received this error, (extend the file system?) it will help us to understand the problem.

Hi Sivagnanaselvan ,

I can't check lvsize with bdf because I can't mount this lv.

This filesystem is new, it's empty. There was no information in it.

Thanks.

Re: fsck error: "file system is larger than device"

Daniel_RP — Fri, 10 Nov 2006 04:28:45 GMT

Sorry, I was confused.
You're right:

bdf /dev/vgHITACHI_P6/lvHIP16

Filesystem kbytes used avail %used Mounted on
/dev/vgHITACHI_P6/lvHIP16
32768000 4192 32251876 0%

Thanks.

Re: fsck error: "file system is larger than device"

siva0123 — Fri, 10 Nov 2006 04:31:14 GMT

Carlos ,

From the fstype o/p i 've calculated your filesystem size

It can be calculated as ((f_bsize*f_size)/1024/1024)

For your case it is ((8192*81920000)/1024/1024) =64000MB

But the vgdisplay -v command reports that your lvsize is 319XX MB ,

So definitely there is a mismatch in your filsystem size and the corresponding lv size.

Try to reduce your filesystem size to 32 GB or increas ethe size of your LV to 64GB

Thanks,
Siva

Yang Qin_1 — Fri, 10 Nov 2006 04:33:47 GMT

From which command you received this error?
Did you run "newfs -F vxfs /dev/vgHITACHI_P6/rlvHIP16"? after you create lvol with lvcreate?

siva0123 — Fri, 10 Nov 2006 04:42:05 GMT

Carol,

I'm not completely right .

Your bdf o/p shows the filsystem size as 32000 MB and the VG display shows your LVsize as 31984MB.

That means you have created a filesystem which is larger than your Logical Volume.

If you say the filesystem is empty why cant you try to recreate the filesystem from the scratch which will be equal to your Logical volume.

Thanks,
Siva

Re: fsck error: "file system is larger than device"

Daniel_RP — Fri, 10 Nov 2006 04:43:48 GMT

fs size & lv size would have to be 31984 Mbytes.

It's not possible to increase lv size to 64 GB.

I will investigate how to reduce file system size to 31984 MB.

Thanks a lot.

I will close this post if I will finish correcly the operation.

Re: fsck error: "file system is larger than device"

Daniel_RP — Fri, 10 Nov 2006 05:02:06 GMT

I run:
# newfs -F vxfs /dev/vgHITACHI_P6/rlvHIP16

version 4 layout
32751616 sectors, 8187904 blocks of size 4096, log size 512 blocks
unlimited inodes, largefiles not supported
8187904 data blocks, 8186800 free data blocks
250 allocation units of 32768 blocks, 32768 data blocks
last allocation unit has 28672 data blocks

And then I tried to fsck lvHIP16:

fsck /dev/vgHITACHI_P6/rlvHIP16

fsck: /etc/default/fs is used for determining the file system type
file system is clean - log replay is not required

fsck is ok!!!

But now I get:"vxfs mount: mount option(s) incompatible with file system /dev/vgHITACHI_P6/lvHIP16"

When trying to mount it: "/usr/sbin/mount -F vxfs -o rw,suid,delaylog,largefiles,datainlog /dev/vgHITACHI_P6/lvHIP16 /p16"

Re: fsck error: "file system is larger than device"

Daniel_RP — Fri, 10 Nov 2006 05:08:55 GMT

Sorry, firstly:

I have ran newfs command without "-o largefiles" parameter.

How Can I change it?

siva0123 — Fri, 10 Nov 2006 05:10:04 GMT

Carlos,

If i'm not wrong i see the filesystem was created with no large file support but you are trying to mount the filesystem with large file support .

Try mounting it without the large files option.

Thanks,
Siva
