Message-ID: <56CB6DC2.8040106@profihost.ag> (raw)
Hello,
is there any chance or hack to work with a bigger cluster size for the
drive backup job?
See:
http://git.qemu.org/?p=qemu.git;a=blob;f=block/backup.c;h=16105d40b193be9bb40346027bdf58e62b956a96;hb=98d2c6f2cd80afaa2dc10091f5e35a97c181e4f5
This is very slow with ceph - may be due to the 64k block size. I would
like to check whether this is faster with cephs native block size of 4mb.
Greets,
Stefan
