Hi!
Glad to hear your Ceph is working again! ;)
BTW, it is a new knowledge: how ceph behave with bad ram.
Do you have memory ECC errors in logs?
Linux has EDAC module (I think, it is enabled by default in Debian) which
reports any machine
errors happening - machine check exeptions, memory error

Hi!
I'm sorry, but I dont know, how to help you. We move OSDs from XFS to EXT4 on
our test
cluster (Hammer 0.94.2), removing ODSs one-by-one and re-adding them after
reformatting
to EXT4. This process is usual to a ceph (Add/Remove OSDs in documentaion) and
took
place without any data loss. We
Hi!
When inconsistent PGs starting to appear? Maybe after some event?
Hang, node reboot or after reconfiguration or changing parameters?
Can you say, what triggers such behaviour? And, BTW, what system/kernel
you use?

If it will lead to read errors, it will be logged in dmesg. If it cause only
SATA command retransmission, it maybe won't logged in dmesg,
but have to be shown in SMART attributes.
And anyway, we face only som
Hi!
Do you have any disk errors in dmesg output? In our practice, every time the
deep
scrub found inconsistent PG, we also found a disk error, that was the reason.
Sometimes it was media errors (bad sectors), one time - bad sata cable and
we also had some raid/hba firmware issues. But in all case
