Re: [ceph-users] Fwd: High IOWait Issue

could you post the result of "ceph -s" ? besides the health status there are other details that could help, like the status of your PGs., also the result of "ceph-disk list" would be useful to understand how your disks are organized. For instance with 1 SSD for 7 HDD the SSD could be the

Re: [ceph-users] Fwd: High IOWait Issue

You have 2 drives at almost 100% util which means they are maxed. So you need more disks or better drives to fix your io issues (SSDs for MySQL is a no brainer really)  -- Ursprungligt meddelande--Från: Sam HuracanDatum: lör 24 mars 2018 19:20Till: c...@elchaka.de;Kopia:

[ceph-users] Radosgw ldap info

To clarify if I understand correctly: It is NOT POSSIBLE to use an s3 client like eg. cyberduck/mountainduck and supply a user with an 'Access key' and a 'Password' regardless if the user is defined in ldap or local? I honestly cannot see how this ldap integration should even work, without

Hi, what version of ceph are you using? what is HW config of your OSD nodes? Have you checked your disks for errors (dmesg, smartctl). What status is the ceph reporting? (ceph -s) What is the saturation level of your ceph ? (ceph dt) Kind regards, Laszlo
