Re: [ceph-users] cephfs (rbd) read performance low - where is the bottleneck?

Have you looked at your file layout? On a test cluster running 10.2.3 I created a 5GB file and then looked at the layout: # ls -l test.dat -rw-r--r-- 1 root root 524288 Nov 20 23:09 test.dat # getfattr -n ceph.file.layout test.dat # file: test.dat ceph.file.layout="stripe_unit=4194304 s

[ceph-users] RadosGW not responding if ceph cluster in state health_error

Re: [ceph-users] Intel P3700 SSD for journals

The SATA S3700 series has been the de-facto for journals for some time. And journals don’t neeed all that much space. We’re using 400GB P3700’s. I’ll say a couple of things: o Update to the latest firmware available when you get your drives, qual it and stick with it for a while so you have a

[ceph-users] ceph osd down

Hi guys, So our cluster always got osd down due to medium error.Our current action plan is to replace the defective disk drive.But I was wondering whether it's too sensitive for ceph to take it down.Or whether our action plan was too simple and crude.Any advice for this issue will be appreciated

[ceph-users] cephfs (rbd) read performance low - where is the bottleneck?

Hi, reading a big file 50 GB (tried more too) dd if=bigfile of=/dev/zero bs=4M in a cluster with 112 SATA disks in 10 osd (6272 pgs, replication 3) gives me only about *122 MB/s* read speed in single thread. Scrubbing turned off during measurement. I have been searching for possible bottlen
