I just did vgchange -an, and there came the oom-killer. This is all
with 2.6.22.5 kernel.
The machine has 256 MB RAM; PV is almost 1.5 TB big:
# pvs
PV VG Fmt Attr PSize PFree
/dev/md0 superthecus lvm2 a- 1.46T 120.63G
After I do "vgchange -ay", the memory usage goes from ~17 MB to almost
180 MB - is it normal?
Can the memory usage be so high (~180 MB out of 256 MB) because I have
two pretty big snapshots? Normally, this machine uses about 17 MB.
# lvs
LV VG Attr LSize Origin Snap% Move Log
Copy%
backup superthecus owi-ao 1.20T
backup-snap superthecus swi-a- 100.00G backup 30.15
backup-snap-resized superthecus swi-a- 30.00G backup 69.00
backup1 superthecus -wi-a- 3.00G
backup1-sync-test superthecus -wi-a- 3.00G
src superthecus -wi-a- 2.00G
swap superthecus -wi-ao 3.00G
Unfortunately, I can't remove these snapshots, as oom-killer comes :(
Is there any solution to that, other than adding memory (which can be
hard to do remotely)?
Ouch - now it went so far that the machine only loops from a kernel
panic to a kernel panic - that's really bad:
(...)
Out of memory: kill process 2220 (getty) score 24 or a child
Killed process 2220 (getty)
Kernel panic - not syncing: Out of memory and no killable processes...
Rebooting in 20 seconds..
