I have a problem while increasing the fileystem. Actually the filesystem is 256 gb
and i have to add another 256 gb.So i got a new lun(hdisk) with 256 gb.
I added to the vg using the extendvg command.
It was successfully added, and when i checked the free pp's in vg it was showing for 256 gb (1023 pp) 1 pp= 256mb .
So when i was giving the chfs to increase it was shown below error,
but when i checked the lv for max pp it was no issue it is showing
MAX LPs: 2046 and also the upperbound value is 16.So everything is fine in lv.
But when i checked the vg o/p again i was shocked that there is no free pp.
but the filesystem also not increased.
My question is,
Will the system need a reboot, or i have to again reduce the disk from vg and need to add?
But for removing the disk from vg i need to check whether the disk is in use? so how to check.
Pls help me out in this...
Thanks in advance...

Now, i know a ufs file system can be increased using mkfs but hwo do I take space from a file system and add it to another file system? at my job here, that seems to be possible because I see request on it almost every day.
what is the exact command to do this and does the system need to be... (1 Reply)
Hi Everybody,
I have AIX 4.3 and I have a FileSystem with 400GB size, which called /db/run. Because of grow up of the application's data, more storage has been added 200GB. To add this space without affecting the application & the application's requirements, I have to add this 200GB to the existed... (9 Replies)

Hi,
I wanted to find out that in my database server which filesystems are shared storage and which filesystems are local. Like when I use df -k, it shows "filesystem" and "mounted on" but I want to know which one is shared and which one is local.
Please tell me the commands which I can run... (2 Replies)
Hi,
I have a strange problem with iscsi.
My vfstab entry looks like this:
/dev/md/dsk/d100 /dev/md/rdsk/d100 /zones/ssapp0895v01 ufs 2 iscsi -
After rebooting, the filesystem gets mounted with the option "nosetuid". I believe the default should be "suid"

There is a shared volume group connected to two AIX systems A and B on a shared storage. The shared volume group was regularly attached to the system A and in case of a system A crash, the system B should take over the shared volume group and resources on it.

xfs_growfs
xfs_growfs(8) System Manager's Manual xfs_growfs(8)NAME
xfs_growfs, xfs_info - expand an XFS filesystem
SYNOPSIS
xfs_growfs [ -dilnrxV ] [ -D size ] [ -e rtextsize ] [ -L size ] [ -m maxpct ] [ -t mtab ] [ -R size ] mount-point
xfs_info [ -t mtab ] mount-point
DESCRIPTION
xfs_growfs expands an existing XFS filesystem (see xfs(5)). The mount-point argument is the pathname of the directory where the filesystem
is mounted. The filesystem must be mounted to be grown (see mount(8)). The existing contents of the filesystem are undisturbed, and the
added space becomes available for additional file storage.
xfs_info is equivalent to invoking xfs_growfs with the -n option (see discussion below).
OPTIONS -d | -D size
Specifies that the data section of the filesystem should be grown. If the -D size option is given, the data section is grown to that
size, otherwise the data section is grown to the largest size possible with the -d option. The size is expressed in filesystem
blocks.
-e Allows the real-time extent size to be specified. In mkfs.xfs(8) this is specified with -r extsize=nnnn.
-i The new log is an internal log (inside the data section). [NOTE: This option is not implemented]
-l | -L size
Specifies that the log section of the filesystem should be grown, shrunk, or moved. If the -L size option is given, the log section
is changed to be that size, if possible. The size is expressed in filesystem blocks. The size of an internal log must be smaller
than the size of an allocation group (this value is printed at mkfs(8) time). If neither -i nor -x is given with -l, the log contin-
ues to be internal or external as it was before. [NOTE: These options are not implemented]
-m Specify a new value for the maximum percentage of space in the filesystem that can be allocated as inodes. In mkfs.xfs(8) this is
specified with -i maxpct=nn.
-n Specifies that no change to the filesystem is to be made. The filesystem geometry is printed, and argument checking is performed,
but no growth occurs. See output examples below.
-r | -R size
Specifies that the real-time section of the filesystem should be grown. If the -R size option is given, the real-time section is
grown to that size, otherwise the real-time section is grown to the largest size possible with the -r option. The size is expressed
in filesystem blocks. The filesystem does not need to have contained a real-time section before the xfs_growfs operation.
-t Specifies an alternate mount table file (default is /proc/mounts if it exists, else /etc/mtab). This is used when working with
filesystems mounted without writing to /etc/mtab file - refer to mount(8) for further details.
-V Prints the version number and exits. The mount-point argument is not required with -V.
xfs_growfs is most often used in conjunction with logical volumes (see md(4) and lvm(8) on Linux). However, it can also be used on a regu-
lar disk partition, for example if a partition has been enlarged while retaining the same starting block.
PRACTICAL USE
Filesystems normally occupy all of the space on the device where they reside. In order to grow a filesystem, it is necessary to provide
added space for it to occupy. Therefore there must be at least one spare new disk partition available. Adding the space is often done
through the use of a logical volume manager.
EXAMPLES
Understanding xfs_info output.
Suppose one has the following "xfs_info /dev/sda" output:
meta-data=/dev/sda isize=256 agcount=32, agsize=16777184 blks
= sectsz=512 attr=2
data = bsize=4096 blocks=536869888, imaxpct=5
= sunit=32 swidth=128 blks
naming =version 2 bsize=4096
log =internal bsize=4096 blocks=32768, version=2
= sectsz=512 sunit=32 blks, lazy-count=1
realtime =none extsz=524288 blocks=0, rtextents=0
Here, the data section of the output indicates "bsize=4096", meaning the data block size for this filesystem is 4096 bytes. This section
also shows "sunit=32 swidth=128 blks", which means the stripe unit is 32*4096 bytes = 128 kibibytes and the stripe width is 128*4096 bytes
= 512 kibibytes. A single stripe of this filesystem therefore consists of four stripe units (128 blocks / 32 blocks per unit).
