Hello Quenten,
Thanks for your reply.
We have a 5GB journal for each OSD on the same disk.
Right now, we are migrating our OSD to XFS and we'll add a 5th monitor. We will
perform the benchmarks afterwards.
Cheers,
Alexandre

thanks, sage weil.
writing fs is a serious matter,we should make it clear, includes coding style.
there are other places we should fix.
thanks

I’m just curious, for such a routine operation, what are most admins doing in
this case?

Dear ceph users,
we are managing ceph clusters since 1 year now. Our setup is typically
made of Supermicro servers with OSD sata drives and journal on SSD.
Those SSD are all failing one after the other after one year :(
We used Samsung 850 pro (120Go) with two setup (small nodes with 2 ssd,

Hi Dan,
At least looking at upstream to get journals and partitions persistently
working, this requires gpt partitions, and being able to add a GPT
partition UUID to work perfectly with minimal modification.
I am not sure the status of this on RHEL6, The latest Fedora and
OpenSUSE support this

Hi Emmanuel,
This is interesting, because we’ve had sales guys telling us that those Samsung
drives are definitely the best for a Ceph journal O_o !
The conventional wisdom has been to use the Intel DC S3700 because of its
massive durability.
Anyway, I’m curious what do the SMART counters say

between 30 and 40 TB ...
Thought, statistics gives 60GB (option 2) to 100 GB (option 1) writes
per day on SSD on a not really over loaded cluster.

Hi Alexandre,
No problem, I hope this saves you some pain
It's probably worth going for a larger journal probably around 20Gig if
you wish to play with tuning of filestore max sync interval could be
have some interesting results.
The issue hasn't popped up since I upgraded the kernel so the issue I was
experiencing seems to have been addressed.

I have a project that requires running 'rbd' on machines that have a fairly

Centos5.10). It would be really

You can test it via ./ceph_test_librbd_fsx and running fsxtest in
