Hi,
While upgrading the monitors on a Nautilus test cluster warning messages
apear:
[WRN] failed to encode map e905 with expected crc
Is this expected?
I have only seen this in the past when mixing different releases (major
versions), not when upgrading within a release.
What is the impact of
Hi
I have question regarding supervised/automatic balancing using upmap.
I created a plan in supervised mode, but its score was not expected to
improve the data distribution. But the automatic balancer triggered a
considerable rebalance.
Is this normal ? I thought that automatic balancing basica
Hi all,
We are using cephfs to make a copy of another fs via rsync, and also use
snapshots.
I'm seeing this issue now and then when I try to delete files on cephFS:
|[root@osd001 ~]# rm -f /mnt/ceph/backups/osd00*||
||rm: cannot remove
‘/mnt/ceph/backups/osd001.gigalith.os-3eea7740.1542483’:
Quoting Kenneth Waegeman (kenneth.waege...@ugent.be):

It's not well balanced though ... do you use ceph balancer (with
balancer in upmap mode)?

Yeah, no ENOSPC error code on deletion is a little bit unintuitive,
but what it means is: the purge queue is full.
You've already told the MDS to purge faster.
Not sure how to tell it to increase the maximum backlog for
deletes/purges, though, but you should be able to find something with

Hello everyone!
After years of running several ZFS pools on a home server and several
disk failures along the way, I've decided that my current home storage
setup stinks. So far there hasn't been any data loss, but
recovering/"resilvering" a ZFS pool after a disk failure is a
nail-biting experienc
I use those HC2 nodes for my home Ceph cluster, but my setup only has to
support the librados API, my software does HSM between regular XFS file systems
and the RADOS api so I don’t need the other MDS and the rest so I can’t tell
you if you’ll be happy in your configuration.

2GB ram is gonna be really tight, probably. However, I do something similar
at home with a bunch of rock64 4gb boards, and it works well. There are
sometimes issues with the released ARM packages (frequently crc32 doesn;'t
work, which isn't great), so you may have to build your own on the board

Bummer. So it won't be enough for any Ceph component to run reliably?
Drat. The nice thing about the HC2 is the fact that it can power the
attached SATA disk and itself through one barrel connecto
