Multi-terabyte filesystem space increase on AIX7.1

Thanks for the reply Robin.
By maximum number of extents I assume you mean MAX LPs?
- That is something I will need to increase when I go to do the filesystem increase.
PP size in the VG is 1024GB. It was originally designed for this size filesystem.
Not sure what you mean by is the volume group protected, but yes it is SAN disk.
As regards "increase to" versus "increase by", as far as I'm aware there is no functional difference (assuming one calculates correctly).
Cheers, Alan.

Hello alanp36,
You might need to look at the maximum number of extents allowed for the logical volume. You might need a chlv -x <<large_value_here>> type command.
A few things to think about:-
There should not be a problem going in one go.

You might need to look at the maximum number of extents allowed for the logical volume. You might need a chlv -x <<large_value_here>> type command.
A few things to think about:-
- What is your PP size for the volume group?
- Can you show us the output for lslv <<lv_name_here>>
- Is your volume group protected? I'm guessing it must be formed from RAID or SAN LUNs, but one should ask
- Would you be better saying "increase by this amount" or "increase to this amount"?
There should not be a problem going in one go.

pvdisplay - display attributes of a physical volume SYNOPSIS
pvdisplay [-c|--colon] [-d|--debug] [-h|-?|--help] [-s|--short] [-v[v]|--verbose [--verbose]] PhysicalVolumePath [PhysicalVolumePath...] DESCRIPTION
pvdisplay allows you to see the attributes of one or more physical volumes like size, physical extent size, space used for the volume group descriptor area and so on. pvs (8) is an alternative that provides the same information in the style of ps (1). OPTIONS
See lvm for common options. -c, --colon Generate colon separated output for easier parsing in scripts or programs. N.B. pvs (8) provides considerably more control over the output. The values are: * physical volume device name * volume group name * physical volume size in kilobytes * internal physical volume number (obsolete) * physical volume status * physical volume (not) allocatable * current number of logical volumes on this physical volume * physical extent size in kilobytes * total number of physical extents * free number of physical extents * allocated number of physical extents -s, --short Only display the size of the given physical volumes. -m, --maps Display the mapping of physical extents to logical volumes and logical extents.
