How to properly resize VG/LV on LVM?
I got logical volume for mailboxes on LVM for easy expanding as
mailboxes are growing. However I can't really resize it, or I don't know
how to do it on NetBSD.
Filesystem Size Used Avail %Cap Mounted on
/dev/mapper/varmailvg-virtuallv 984G 860G 74G 92%
I already extended disk on Xen Level from 1000GB to 1200GB, and dmesg is
showing it correctly:
xbd3 at xenbus0 id 51776: Xen Virtual Block Device Interface
xbd3: using event channel 11
xbd3: 1200 GB, 512 bytes/sect x 2516582400 sectors
xbd3: WARNING: cache flush not supported by backend
Then I run:
# lvm pvresize /dev/rxbd3a
Physical volume "/dev/rxbd3a" changed
1 physical volume(s) resized / 0 physical volume(s) not resized
which looks good, but lvm pvs still shows 1000GB instead of 1200GB
# lvm pvs
PV VG Fmt Attr PSize PFree
/dev/rxbd3a varmailvg lvm2 a- 1000.00g 1020.00m
Probably I should "resize in place" with disklabel or fstab after
extending in Xen but I don't know exactly how. There is also resize_ffs
somewhere in a process I think.
Is there any guide for NetBSD how to properly extend lvm volume?
