Hi,
There are any way to set permission that don't allow users to create
buckets but they can read these buckets? and how to add prefix to a bucket
when users create one, ex: when user 'aa' create a bucket called 'testing',
bucket name will be 'aatesting'?
Best regards,
Thanh Tran
Thank you soo much! That seems to work immidetately.
ATM I still see 3 pgs in active+clean+scrubbing state - but that will
hopefully fix by time.
So the way to go with firefly, is to either use at least 3 hosts for
OSDs - or reduce the number of replicas?
Kind Regards,
Georg

Leen,
thanks for explaining things. I does make sense now.
Unfortunately, it does look like this technology would not fulfill my
requirements as I do need to have an ability to perform maintenance without
shutting down vms.
I will open another topic to discuss possible solutions.
Thanks
Hello guys,
I am currently running a ceph cluster for running vms with qemu + rbd. It works
pretty well and provides a good degree of failover. I am able to run
maintenance tasks on the ceph nodes without interrupting vms IO.
I would like to do the same with VMWare / XenServer hypervisors,
Hi,
at the moment we are using tgt with RBD backend compiled from source on Ubuntu
12.04 and 14.04 LTS. We have two machines within two ip-ranges (e.g.
192.168.1.0/24 and 192.168.2.0/24). One machine in 192.168.1.0/24 and one
machine in 192.168.2.0/24. The config for tgt is the same on both
Hi,
I want to create a block image using the rbd cli and followng the rule:

But when I try to map to a block device then raise

Been doing some reading on the CEPH documentation and just wanted to clarify if

Uwe, thanks for your quick reply.
Do you run the Xenserver setup on production env and have you tried to test
some failover scenarios to see if the xenserver guest vms are working during
the failover of storage servers?
Also, how did you set up the xenserver iscsi? Have you used the
Hello Andrei,
I'm trying to accomplish the same thing with VMWare. So far I'm still doing
lab testing, but we've gotten as far as simulating a production workload.
Forgive the lengthy reply, I happen to be sitting on an airplane .
My existing solution is using NFS servers running in ESXi VMs.

Hello, last week I've upgraded from 0.72.2 to last stable firefly 0.80

Everything is ok, I've HEALTH_OK on both, the only weird thing is that
few PGs remain in active+clean+scrubbing.

yes, we use it in production. I can stop/kill the tgt on one server and
XenServer goes to the second one. We enabled multipathing in xenserver. In our

The formula was designed to be used on a per-pool basis. Having said that,
though, when looking at the number of PG's from a system-wide perspective, one
does not want too many total PG's. So, it's a balancing act, and it has been
suggested that it's better to have slightly more PG's than you
We are using a switchstack of Juniper EX4200 and EX3200. Cisco should work,
too. Anotheroption is failover bonding (but multipathing with different ips is
better)

Thanks for the info. I was erring to less pools but using software that does
not share pools very well seem to put a spanner in the works at the time. I

being a problem that prevents scrub from completing in some cases.
