Re: [ceph-users] CEPH Cluster Usage Discrepancy

Awesome! Thanks Serian! Do you know where the 64KB comes from? Can that be tuned down for a cluster holding smaller objects? Get Outlook for iOS On Sat, Oct 20, 2018 at 10:49 PM -0700, "Serkan Çoban" mailto:cobanser...@gmail.com>> wrote: you have 24M objects, not 2.4

Re: [ceph-users] Verifying the location of the wal

Thanks Serkan. I am using --path instead of --dev (dev won't work because I'm using VGs/LVs). The output shows block and block.db, but nothing about wal.db. How can I learn where my wal lives? On Sun, Oct 21, 2018 at 12:43 AM Serkan Çoban wrote: > ceph-bluestore-tool can show you the disk

Thanks Sergey! Do you know where I can find details on the repercussions of adjusting this value? Performance (read/writes), for once, not critical for us, data durability and disaster recovery is our focus. -Dan Get Outlook for iOS On Sun, Oct 21, 2018 at 8:37 AM -07

Re: [ceph-users] Verifying the location of the wal

wal and db device will be same if you use just db path during osd creation. i do not know how to verify this with ceph commands. On Sun, Oct 21, 2018 at 4:17 PM Robert Stanford wrote: > > > Thanks Serkan. I am using --path instead of --dev (dev won't work because > I'm using VGs/LVs). The outp

Re: [ceph-users] CEPH Cluster Usage Discrepancy

It is just a block size and it has no impact on data safety except that OSDs need to be redeployed in order for them to create bluefs with given block size. > On 21.10.2018, at 19:04, Waterbly, Dan wrote: > > Thanks Sergey! > > Do you know where I can find details on the repercussions of adju

Re: [ceph-users] Verifying the location of the wal

I did exactly this when creating my osds, and found that my total utilization is about the same as the sum of the utilization of the pools, plus (wal size * number osds). So it looks like my wals are actually sharing OSDs. But I'd like to be 100% sure... so I am seeking a way to find out On Sun
