Hi,
With the release of 12.2.12 the bitmap allocator for BlueStore is now
available under Mimic and Luminous.
[osd]
bluestore_allocator = bitmap
bluefs_allocator = bitmap
Before setting this in production: What might the implications be and
what should be thought of?
>/From what I've read the bitmap allocator seems to be better in read
/performance and uses less memory.
In Nautilus bitmap is the default, but L and M still default to stupid.
Since the bitmap allocator was backported there must be a use-case to
use the bitmap allocator instead of stupid.
Thanks!
Wido
Wido, do you setted allocator to bitmap on L installations past this
months? Any improvements?
