Yes, sorry, extents is more of an Oracle space allocation.
The difference in "increase to" and "increase by" determines if you do this:-
Code:
chfs -a size=15000G /your_fs
... or this:-
Code:
chfs -a size=+15000G /your_fs
The former sets the new size and the latter sets the increase in size, so depending what you start with, there could be quite a difference.
I think you have a good plan and I think that the suggestion from agent.kgb is very sensible. Maybe stop short and do the last 2 extensions yourself. Ensure you don't over-allocate the filesystem. When I last had AIX, reducing a filesystem was not possible - you had to drop & re-create it.
SAN disk is (almost always) provided by protected disk, so probably RAID5 or RAID10 etc., but if you have SAN disk, it is not the concern of the person managing the AIX server, so that makes things easier.

Hi All,
I need to increase the filesystem of / and /var (two different slices)? Space will be coming from /home slice so I need to decrease it. Is that possible without reinstallation or in a single-user-mode?
Any idea or link please.
Thanks in advance. (5 Replies)

mkfs.btrfs
MKFS.BTRFS(8) System Manager's Manual MKFS.BTRFS(8)NAME
mkfs.btrfs - create an btrfs filesystem
SYNOPSIS
mkfs.btrfs [ -A alloc-start ] [ -b byte-count ] [ -d data-profile ] [ -l leafsize ] [ -L label ] [ -m metadata profile ] [ -n nodesize
] [ -s sectorsize ] [ -h ] [ -V ] device [ device ... ]
DESCRIPTION
mkfs.btrfs is used to create an btrfs filesystem (usually in a disk partition, or an array of disk partitions). device is the special file
corresponding to the device (e.g /dev/sdXX ). If multiple devices are specified, btrfs is created spanning across the specified
devices.
OPTIONS -A, --alloc-start offset
Specify the offset from the start of the device to start the btrfs filesystem. The default value is zero, or the start of the
device.
-b, --byte-count size
Specify the size of the resultant filesystem. If this option is not used, mkfs.btrfs uses all the available storage for the filesys-
tem.
-d, --data type
Specify how the data must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.
-l, --leafsize size
Specify the leaf size, the least data item in which btrfs stores data. The default value is the page size.
-L, --label name
Specify a label for the filesystem.
-m, --metadata profile
Specify how metadata must be spanned across the devices specified. Valid values are raid0, raid1, raid10 or single.
-n, --nodesize size
Specify the nodesize. By default the value is set to the pagesize.
-s, --sectorsize size
Specify the sectorsize, the minimum block allocation.
-V, --version
Print the mkfs.btrfs version and exit.
AVAILABILITY
mkfs.btrfs is part of btrfs-progs. Btrfs is currently under heavy development, and not suitable for any uses other than benchmarking and
review. Please refer to the btrfs wiki http://btrfs.wiki.kernel.org for further details.
