Unable to allocate hash table space
i.e. There wasn't enough memory available to set up the snapshot.
What sizes: How big is the LV & snapshot?
main partition is 500GB and I've two snapshots, weekly that is 100G and
daily that is 60G
What chunk size? [Try changing.]
chunk is 8.00 KB (what is the suggested value ??)
Is there just one snapshot?
as I wrote there are two..
Check your memory usage.
my hardware memory is almost full 860/1000, but the swap isn't that used
(it's now 3.3/2000) do the device mapper need more real mem ?? does it
worth to increase the swap ?
tnx,
