[ceph-users] Re: Recovering from a Failed Disk (replication 1)

I think your better off doing the DD method, you can export and import a PG at a time (ceph-objectstore-tool) But if the disk is failing a DD is probably your best method. On Thu, 17 Oct 2019 11:44:20 +0800 vladimir franciz blando wrote Sorry

Sorry for not being clear, when I say healthy disk, I mean those are already an OSD, so I need to transfer the data from the failed OSD to the other OSDs that are healthy. - Vlad ᐧ On Thu, Oct 17, 2019 at 11:31 AM Konstantin Shalygin wrote: > > On 10/17/19 10:29 AM, vladimir franciz blando

[ceph-users] Recovering from a Failed Disk (replication 1)

Hi, I have a not ideal setup on one of my cluster, 3 ceph nodes but using replication 1 on all pools (don't ask me why replication 1, it's a long story). So it has come to this situation that a disk keeps on crashing, possible a hardware failure and I need to recover from that. What's my best

[ceph-users] Please help me understand this large omap object found message.

I've been searching around trying to learn about this, but it doesn't seem to be in index sharding problem, so I'm not sure how to approach it and I'm still new to RGW. This is what is in the cluster logs: Large omap object found. Object:

I have clusters mixing with no problems. At one point we bought a SAS model, when we don’t have a local exact spare we replace dead ones with SATA. Some HBAs or backplanes though might not support mixing. Unlike crappy HBA RoC vols, Ceph doesn’t care. > On Oct 16, 2019, at 1:39 PM,

I have inherited a cluster where about 30% of the osds in a pool are 7200 SAS. The other 70% are 7200 SATA. Should I look into creating 2 pools or will this likely not be a huge deal? ___ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send

This does sound like a network problem. Try increasing log levels for mon (debug_mon = 10/10) and maybe the messenger (debug_ms=5/5 or 10/10, very noisy, to see where it is stuck) Paul -- Paul Emmerich Looking for help with your Ceph cluster? Contact us at https://croit.io croit GmbH

S3 is not a browser friendly protocol. There isn't a way to get user-friendly output via the browser alone, you need some form of client that speaks the S3 REST protocol. The most commonly used one by us is s3cmd, which is a command line utility. A quick google search finds some web-based

This is not quite true. The numberspace of MD5 is much greater than 2³², (2¹²⁸ exactly) and as long as you don't exhaust this Numberspace, the probability of having a collision is roughly equally likely as with any other input. There might be collisions, and the more Data you have, i.e. the
