Filesystem extension issues in HP-UX

Filesystem extension issues in HP-UX

I am getting the below error when extending the filesystem on HP-UX .

UX:vxfs fsadm: ERROR: V-3-20340: attempt to resize /dev/vgtest/rlvtest1 failed with errno 16.

What could be the issue here  ?

   As usual, showing an actual command can be more helpful than a vague
description.

      uname -a

   I know nothing, but errno 16 is EBUSY, "Mount device busy".

Re: Filesystem extension issues in HP-UX

If you are trying to use the 'extendfs' command on the LV, then you must first unmount the LV.

Re: Filesystem extension issues in HP-UX

If the mountpoint you are extending has been exported using NFS or SAMBA, it will be marked as busy. The mountpoint must un-exported before you can extend it.

Re: Filesystem extension issues in HP-UX

Hi All,

Here the command used to extend the filesystem and failure message.

root@testserv1[/] # lvextend -L 35840M /dev/vgtest/lvtest1
Logical volume "/dev/vgtest/lvtest1" has been successfully extended.
Volume Group configuration for /dev/vgtest has been saved in /etc/lvmconf/vgtest.conf
root@testserv1[/] # fsadm -F vxfs -b 35840M /test1
UX:vxfs fsadm: ERROR: V-3-20340: attempt to resize /dev/vgtest/rlvtest1 failed with errno 16
root@testserv1[/] #

This Filesystem is not shared as NFS & Samba. I am using lvextend & fsadm to extend the filesystem.

HP-UX Version is B.11.31.

This filesystem snaped with other filesystem. Please let me know the procedure to extend .

root@testserv1[/] # mount -v |grep -i test1
/dev/vgtest/lvtest1 on /test1 type vxfs ioerror=mwdisable,largefiles,delaylog,dev=80000003 on Sat Feb 6 13:08:11 2016

root@testserv1[/] #

Aplogies for the late reply

Re: Filesystem extension issues in HP-UX

What is the solution for this error, I notice someone faced the same issue.

(root) @/> fsadm -F vxfs -b 330227968 /oracle
UX:vxfs fsadm: ERROR: V-3-20340: attempt to resize /dev/vgoracle/rlvoracle failed with errno 16
(root) @/>

Defragmented, still no help..

Thank you in advance!

Re: Filesystem extension issues in HP-UX

The error means device busy. Sure you have OnlineJFS?

 


Hope this helps!

Re: Filesystem extension issues in HP-UX

Yes, have online JFS as I was able to do 5 filesystems and other 5 filesystems failed with the same error mentioned above.

All the ten file systems are from one volume group, and out of 10 successfully I was able to extend FS size on five and the other five failed with error 16. 

Help is appreciated.

Re: Filesystem extension issues in HP-UX

Your command:

fsadm -F vxfs -b 330227968 /oracle

is to resize the /oracle mountpoint to 330 million sectors. Is that correct?
Or did you mean 330 GB? If so, you'll need to use a suffix such as -b 330G.

Also, is /oracle a top level filesystem or does it contain other lvols or NFS mounts?
      hint:    bdf   /oracle
That will show the source lvol for the mountpoint.

And did you first increase the source lvol size first using lvextend?

Re: Filesystem extension issues in HP-UX

It was 220Gig before and I extended 100Gig to the lvm and so extending to 330Gig with fsadm

Re: Filesystem extension issues in HP-UX

Is there a reason that the rather unusual number 330227968  is being used?
fsadm has been historically unstable due to the "sectors" terminology.
Prior to HP-UX 11.31, the man page was very bad as it failed to document the secret option modifiers.
From 11.23:

 -b newsize  Resize the file system to newsize sectors.  
                     -b cannot  be used with the -cdDeEo options.

And from 11.11:

 -b newsize  Resize the file system to newsize sectors.

Is a sector 256 bytes? 512 bytes? 1024 bytes? 2048 bytes? How about 4096 byes?
The term sector is commonly used with disk hardware and is independent from commands used in HP-UX.
There are several man pages that mention "sector" but the exact value is not an stable term.
Here are the 1m man pages that mention sector:

diskinfo.1m
disksecn.1m
extendfs_hfs.1m
extendfs_vxfs.1m
format.1m
fsadm_vxfs.1m
mkfs_hfs.1m
mkfs_vxfs.1m
mount_vxfs.1m
ncheck_hfs.1m
ncheck_vxfs.1m
newfs_hfs.1m
newfs_vxfs.1m
umount_vxfs.1m
vxassist.1m
vxdisk.1m
vxdisksetup.1m
vxdiskunsetup.1m
vxintro.1m
vxmake.1m
vxprint.1m
vxrecover.1m
vxtunefs.1m
vxvol.1m

S the use of sectors as a metric is too unreliable for an exact meaning.
The fsadm man page never defines what a sector is. 


Always use fsadm -b with a dependable metric as in: -b 320000M or -b 320G

Re: Filesystem extension issues in HP-UX

Without the actual error message, I can only guess that it was the same message.
Post the output from vgdisplay for that lvol. Is this lvol perhaps a distributed layout? What does the command: fstyp /dev/vg00/xyz (where xyz is the knoll name) report?

Re: Filesystem extension issues in HP-UX

From lvdisplay: LV Size (Mbytes) 324864

The size error is a possible clue. How about using -b 310G or -b 300G

Also, post the vgdisplay summary too.

Re: Filesystem extension issues in HP-UX

how about the output of

# mount

when you grow the diskspace, did you grow the vg and lvol too?

Hope this helps!

Re: Filesystem extension issues in HP-UX

Ofcourse, I exetended volume group and then logical volume and then fsadm, thats where it is failing.

Re: Filesystem extension issues in HP-UX

Check for possible show stoppers:

  • The file system has active mounted checkpoints
  • File system has been flagged as requiring an FSCK in the superblock
  • The file system is too busy for resize locks to be obtained

 

A suggested solution would be

unmount the file system, perform "fsck -o full", remount, and try again.

Re: Filesystem extension issues in HP-UX

I googled this:

 

https://sort.veritas.com/public/documents/sfha/6.0/aix/productguides/html/sfcfs_install/ch11s04s05.htm

 

A clean_value value of 0x5a indicates the file system is clean. A value of 0x3c indicates the file system is dirty.


Hope this helps!
