Hi,
With my testing cluster (Hammer on Ubuntu 14.04), I have this:

Hi,
We are thinking about a ceph infrastructure and I have questions.
Here is the conceived (but not yet implemented) infrastructure:

yes I know, but to late now, I'm afraid :)

Have you looked into the samsung 845 dc? They are not that expensive last
time I checked.

might be true, yes - we had Intel 128GB (intel S3500 or S3700) - but these
have horrible random/sequetial speeds - Samsun 850 PROs are 3 times at
least faster on sequential, and more than 3 times faser on random/IOPS
measures.
And ofcourse modern enterprise drives = ...

Yes, it sure is - my experience with 'consumer' SSD is that they die
with obscure firmware bugs (wrong capacity, zero capacity, not detected
in bios anymore) rather than flash wearout. It seems that the
'enterprise' tagged drives are less inclined to suffer this fate.

Thanks to all for your reply
It is clear that Monitor keeps track of Pools and PGs in the cluster and there
is no need of MDS for Ceph object storage and block storage, since both of
these storage types do not require to maintain a file hierarchy.But, I have a
question:In Ceph Object Storage, If
these 2 drives, are on the regular SATA (on board)controler, and beside
this, there is 12 x 4TB on the fron of the servers - normal backplane on
the front.
Anyway, we are going to check those dead SSDs on a pc/laptop or so,just to
confirm they are really dead - but this is the way they die, not we
heh :) yes, intresting last name :)
anyway, all are the exact same age, we implememnted new CEPH nodes at
exactly same time - but it's now wearing problem - the dead SSDs were siply
DEAD - smartctl-a showing nothing, except 600 PB space/size :)

If the same chassi/chip/backplane is behind both drives and maybe other
drives in the chassi have troubles,it may be a defect there as well.

Damn… but maybe your surname says it all - Don’t Panic :) But making sure same
