UX:vxfs fsadm: ERROR: attempt to resize /dev/vx/rdsk/xxx/xxx fails with errno 16


The vxfs filesystem cannot be resized

Error Message

# /etc/vx/bin/vxresize -g testdg test +10g
UX:vxfs fsadm: ERROR: V-3-20340: attempt to resize /dev/vx/rdsk/testdg/test failed with errno 16
VxVM vxresize ERROR V-5-1-7514 Problem running fsadm command for volume test, in diskgroup testdg


The full fsck flag is set.

This can be confirmed as below

#echo "8192B.p S" | fsdb -F vxfs /dev/vx/dsk/testdg/test | grep -i clean 

flags 101 mod 0 clean 3c

The actual device can be obtained from the /etc/fstab file.

The key is the flags field. In this case it is "101", which breaks down to mean: VX_FULLFSCK | VX_METAIOERR | VX_DATAIOERR per the following defines:

VX_FULLFSCK     0x0001                       full fsck required
VX_LOGBAD        0x0002                       log is invalid, do not do replay
VX_NOLOG          0x0004                        no logging, do not do replay
VX_RESIZE          0x0008                         resize in progress
VX_LOGRESET    0x0010                        log reset desired
VX_UPGRADING  0x0020                       upgrade in progress
VX_UQUOTACHECK  0x0040                V2 only, moved to CUT in V3
VX_GQUOTACHECK  0x0080                V2 only, moved to CUT in V3
VX_METAIOERR   0x0100                     file system meta-data i/o error
VX_DATAIOERR    0x0200                    file data i/o error




1. It is now known that this file system has corruption, it is a good idea to perform a full backup of your data. 

Also recommended is to dump the metadata with the "metasave" utility located at ftp.veritas.com as /pub/support/metasave.tar.Z.  Saving the metadata is a good idea in case there are problems with fsdb later on.

2. Unmount the file system run a full fsck with the -n option to see which inodes are marked bad

fsck -F vxfs -n /dev/vx/rdsk/testdg/test | grep "marked bad"

If there is a lot of corruption then Technical Support Team should be contacted

3. Run a full fsck this will clear the full fsck flag set on the filesystem

fsck -F vxfs -y /dev/vx/rdsk/test/testdg

4.Mount & Resize the filesystem
