I am complete rebuild my storage.
As base: ext4 over mdadm-raid1
Gluster volume in distributed-replicated mode with settings:
As result, I got write performance about 80MB/s on dd if=/dev/zero
of=testfile.bin bs=100M count=10, but I also got some strange things.
If I try to execute above command inside virtual machine (KVM), first time
all going right - about 900MB/s (cache effect, I think), but if I run this
test again on existing file - task (dd) hungs up and can be stopped only by
Overall virtual system latency is poor too. For example, apt-get upgrade
upgrading system very, very slow, freezing on "Unpacking replacement" and
other io-related steps.
Does glusterfs have any tuning options, that can help me?
