Re: [ceph-users] Ceph RBD LIO ESXi Advice?

You might find NFS even slower as you will probably have 2IO's for every ESXi IO due to the journal for whatever FS you are using on the NFS server. If you are not seeing it even slower, you most likely have the NFS server set to run in async mode. > -Original Message- > From: ceph-user

Re: [ceph-users] Erasure coded pools and 'feature set mismatch' issue

With that release it shouldn't be the EC pool causing trouble; it's the CRUSH tunables also mentioned in that thread. Instructions should be available in the docs for using older tunable that are compatible with kernel 3.13. -Greg On Saturday, November 7, 2015, Bogdan SOLGA wrote: > Hello, every

Hi, Craig: I used 10 VMs for federated gateway testing. There are 5 nodes for us-east, and the others are for us-west. The two zones are independent. Before the configurations of the region and zone, I have the two zones with the same 'client.radosgw.[zone]' setting of ceph.conf.

Hello Greg! Thank you for your advice, first of all! I have tried to adjust the Ceph tunables detailed in this page, but without success. I have tried both '*ceph osd crush tunables optimal*' and '*ceph osd crush tunables hammer*', bu

Re: [ceph-users] Erasure coded pools and 'feature set mismatch' issue

The problem is that "hammer" tunables (i.e. "optimal" in v0.94.x) are incompatible with the kernel interfaces before Linux 4.1 (namely due to straw2 buckets). To make use of the kernel interfaces in 3.13, I believe you'll need "firefly" tunables. -- Adam On Sun, Nov 8, 2015 at 11:48 PM, Bogdan SO
