querying tiered EC pool info?

Is there a ceph command to fetch the cache-tier information for an EC pool? For example, you add a tier with ceph osd tier add ..., but there doesn't appear to be an equivalent get operation. Likewise, getting the tier cache-mode or overlay doesn't appear possible with the current tools in

Re: Inline dedup/compression

For compression, I prefer to implement it in ECpool, it is much easier because objects in ECpool are already striped, which is what we have already finished now(and in testing). And the only Append write operation is allowed in EC, which is also lead us to implement it conveniently. Moreover, as

Re: load-gen from an osd node

Hmm, the only changes I see between those two versions are some pretty precise cleanups which shouldn't cause this. But it means that a bisect or determined look should be easy. Can you create a ticket which includes the exact output you're seeing and the exact versions you're running? -Greg On

RE: Probable memory leak in Hammer write path ?

Hi, I think I am eventually able to figure out what is happening.. First, here is the step to reproduce it in any kernel (not specific to 3.16/3.18 as I said earlier) 1. In a SSD create a big journal partition say 20 GB or so. 2. Make all the filestore/journal parameter default other than the

Hi Ken, The commits with a + are found in v0.94.1.3 and are not in hammer (the previous mail related to v0.94.1.2 can be found at http://www.spinics.net/lists/ceph-devel/msg24489.html) $ git rev-parse ceph/hammer 72ecd522941156c8a7e5303531944b0735dcbeb8 $ git --no-pager cherry -v ceph/hammer

RE: Probable memory leak in Hammer write path ?

Thanks Greg! Yeah, I will double check..But, I built the code without tcmalloc (with glibc) and it was also showing the similar behavior. Thanks Regards Somnath -Original Message- From: Gregory Farnum [mailto:g...@gregs42.com] Sent: Wednesday, July 01, 2015 9:07 AM To: Somnath Roy Cc:
