Ceph logging level

2013-01-02 Thread Sébastien Han
Hi all, I've been struggling with Ceph logging. As far as I saw we can log to syslog but we can't specify any facility. So my question is: which facility does ceph use by default? Second thing is, I'm sick of all those log [INF] messages from the ceph-mon, like: Jan 2 13:27:07 ceph02

EU mirror issues

Hi all, I just noticed that the sync process for eu.ceph.com didn't work properly. The problem seems to be a faulty rsync script on my side which caused the debian directory not to be synced properly. I corrected the issue, but it has to re-sync again now, that will take some time. The

Very intensive I/O under mon process

2013-01-02 Thread Andrey Korolyov
I have just observed that ceph-mon process, at least bobtail one, has an extremely high density of writes - times above _overall_ cluster amount of writes, measured by qemu driver(and they are very close to be fair). For example, test cluster of 32 osds have 7.5 MByte/s of writes on each mon node

Hi Sage, Thanks for your answer. LOG_USER is currently hard-coded. It would be pretty easy to make this configurable... LOG_DAEMON may also be a better default choice. LOG_DAEMON will be a better choice and even better using a different facility to isolate ceph logs from other services that
