Increase file system size question - exceed max LP error
|

| Anthony Stevenson 2004-08-06, 5:54 pm |
| Hi,
I was told that to increase the size of the file system, use chfs
command and we don't need to touch the logical volume. The only time we
need to touch the logical volume is we exceed the max LPs.
My questions are:
1) Where can I find the max LPs information, using what command?
2) How can I check if the max LPs is exceeded before increasing the file
system?
3) What value of "max LP" I should set to before I can successfully add
file system disk space? Basically how to calculate the right value.
What is the command for setting it? How will I know if the logical
volume is big enough to accomodate the increase in max LP?
4) How does max LPs correlates to physical volume or the available hard
disk size?
Thanks for your help.

There's no standard logical volume software on UNIX. What OS and
revision are you running? The concept of LPs, IIRC, is specific to AIX.

That's only true if your filesystem is smaller than the logical
volume it was created in. Who ever creates a filesystem smaller
than it can be? Noone I know of. Unless you know for sure it's
smaller than the LV, assume it fills it.

You need to say what UNIX and what LVM before anyone can answer
that. LVMs and their commands are unified.

df tells the size of the filesystem as should fsadm. Your system's
LV commands will tell about the LV.

The OP posted that they running AIX 4<something>. Poor sod.
