cluster performance degradation
- Thread starter toto-ets
- Start date
in the activities window it does not exist, this problem occurred when ceph was under construction and the vm was not reachable, I would like to try to restart the node but I'm afraid, do I finish all the bkp first, or can I do something else to change the status?
Can you suggest me the best ZFS configuration? I'm doing DAIDZ with 5 16TB HDDs, what type of compression should I use to get more performance? By default it's on, but it seems to me that lz4 is better or am I wrong? Can you suggest me?
How much do I increase performance like this, from raidz to raid 10? And above all, what compression should I use? Should I leave it on by default?

if it's around 50% it's worth it then losing 3 HDDs on the total, but at least I'll have more performance
I would say 10% performance win but 50% capacity win with compression which defaults to lz4.
Assume often used 10 disk combi in zfs 5 vdev 2-mirror come to 50% but with compression get up 50% from there and you are at 75% (-5% should never used)- so that's near which in raid6 gets 80% space for.

My intention is to have more performance at the expense of space if necessary, so which path should I take?
