Thank you for the reply.
This cluster still is on hammer 0.94.11. I do have both kernel clients
and libvirt based systems using it. Unfortunately that makes balancer
module out of the question (I am aware of it though).
I have couple of those (jewel / hammer) in production that are coming
Which version of Ceph are you running? Do you have any kernel clients? If
yes, can which version kernel? These questions are all leading to see if
you can enable the Luminous/Mimic mgr module balancer with upmap. If you
can, it is hands down the best way to balance your cluster.

If your had a specific location for the wal it would show up there. If
there is no entry for the wal, then it is using the same seeing as the db.

Mehmet: it doesn't look like wal is mentioned in the osd metadata. I see
bluefs slow, bluestore bdev, and bluefs db mentioned only.

We accidentally found ourselves upgraded from 12.2.8 to 13.2.2 after a
ceph-deploy install went awry (we were expecting it to upgrade to 12.2.9 and
not jump a major release without warning)
Anyway .. as a result, we ended up with an mds journal error and 1 daemon
reporting as damaged

As a little "heads-up":
If you are running Ubuntu Bionic 18.04, or Xenial 16.04 with "HWE"
kernels, and have systems running under 4.15.0-36 - which was the
default between 2018-10-01 and 2018-10-22 - please consider upgrading to
the latest 4.15.0-38 ASAP (or downgrade to 4.15.0-34).

This feature is forthcoming with the Nautilus release of Ceph:

You can also use "rbd disk-usage " to compute the
usage of a snapshot.

Hi,
with Filestore, to estimate the weight of snapshot we use a simple find
script on each OSD :
nice find "$OSDROOT/$OSDDIR/current/" \
-type f -not -name '*_head_*' -not -name '*_snapdir_*' \
-printf '%P\n'
Then we agregate by image prefix, and obtain an estimation of each
IIRC there is a Command like

The only way to check this is to check each individual object the RBD
consists of:
rbd info /
--> block_name_prefix: rbd_data.XX
rados -p rbd stat rbd_data.X.
rados -p rbd stat rbd_data.X.0001
rados -p rbd stat rbd_data.X.000
Hi!
Is there an easy way to check when an image was last modified?
I want to make sure, that the images I want to clean up, were not used for
a long time.
Kind regards

Hello Mike, Jason,
Assuming we adapt the current LIO configuration scripts and put QLogic HBAs in
our SCSI targets, could we use FC instead of iSCSI as a SCSI transport protocol
with LIO ? Would this still work with multipathing and ALUA ?
Do you see any issues coming from this type of configura
