Hi List,
If I set in lvm.conf
----------------------------
metadata {
stripesize = 1024
}
----------------------------
it results in correct stripesize:
----------------------------
# lvcreate --name fixi3 -V 10G -T levg/mythinpool
Using default stripesize 1,00 MiB.
WARNING: Sum of all thin volume sizes (7,67 TiB) exceeds the size of
thin pools and the size of whole volume group (901,17 GiB)!
For thin pool auto extension activation/thin_pool_autoextend_threshold
should be below 100.
Logical volume "fixi3" created.
----------------------------
BUT
----------------------------
# lvcreate --stripesize 1024 --name fixi4 -V 10G -T levg/mythinpool
Command does not accept option: --stripesize 1024.
----------------------------
So setting stripesize in lvm.conf is allowed, in lvcreate
(thinpool-mode) not.
What is the right one?
Tfh!
