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)

Hi all,
Do i need to increase the logical volume each time i increase the filesystem?
or is enough to increase the filesystem and the logical volume get increase automatically?

prealloc
prealloc(1) General Commands Manual prealloc(1)NAME
prealloc - preallocate disk storage
SYNOPSIS
name size
DESCRIPTION
preallocates at least size bytes of disk space for an ordinary file name, creating the file if name does not already exist. The space is
allocated in an implementation-dependent fashion for fast sequential reads and writes of the file.
fails and no disk space is allocated if name already exists and is not an ordinary file of zero length, if insufficient space is left on
disk, or if size exceeds the maximum file size or the file size limit of the process (see ulimit(2)). The file is zero-filled.
DIAGNOSTICS
returns one of the following values upon completion:
0 Successful completion.
1 name already exists and is not an ordinary file of zero length.
2 There is insufficient room on the disk.
3 size exceeds file size limits.
EXAMPLES
The following example preallocates 50000 bytes for the file
WARNINGS
Allocation of file space is highly dependent on current disk usage. A successful return does not indicate how fragmented the file actually
might be if the disk is approaching its capacity.
