Hello everybody,
[fix confusing typo]
I got a tree node ceph cluster made of E3-1220v3, 24GB ram, 6 hdd osd's
with 32GB Intel Optane NVMe journal, 10GB networking.
I wanted to move to bluestore due to dropping support of filestore, our
cluster was working fine with filestore and we could take complete nodes
out for maintenance without issues.
root@ceph04:~# ceph osd pool get libvirt-pool size
size: 3
root@ceph04:~# ceph osd pool get libvirt-pool min_size
min_size: 2
I removed all osds from one node, zapping the osd and journal devices,
we recreated the osds as bluestore and used a small 5GB partition as
block device instead of journal for all osd's.
I saw the cluster suffer with pgs inactive and slow request.
I tried setting the following on all nodes, but no diffrence:
ceph tell osd.* injectargs '--osd_recovery_max_active 1'
ceph tell osd.* injectargs '--osd_recovery_op_priority 1'
ceph tell osd.* injectargs '--osd_recovery_sleep 0.3'
systemctl restart ceph-osd.target
How can I migrate to bluestore without inactive pgs or slow request. I
got several more filestore clusters and I would like to know how to
migrate without inactive pgs and slow reguests?
As a side question, I optimized our cluster for filestore, the Intel
Optane NVMe journals showed good fio dsync write tests, does bluestore
also use dsync writes for rockdb caching or can we select NVMe devices
on other specifications? My test with filestores showed that Optane NVMe
SSD was faster then the Samsung NVMe SSD 970 Pro and I only need a a few
GB for filestore journals, but with bluestore rockdb caching the
situation is different and I can't find documentation on how to speed
test NVMe devices for bluestore.
Kind regards,
Jelle
