Hi So I was able to work out how to get the new drive back in CEPH. using a HP bases controller using the CCCISS driver. This is a quick overview of the steps I took Remove data from Dying Drive: ceph osd crush reweight osd.{ID} 0 Remove Dead/Dying Drive (or use the GUI): ceph osd out osd.{ID}...

This is for luminous release I'm running hammer as indicated and I've run the prepare command it failed because Proxmox 4.4 ceph supporting config meaning the cluster does not get set.

What steps do I need to do to get the drive added using manual ceph commands? The links given do not give any real answers to the problem.

So I was able to remove the drive but now I have an issue, related to the cciss drives used by the controller and Proxmox. The same error happens in the GUI. root@blade1:~# ceph-disk zap /dev/cciss/c0d2 Caution: invalid backup GPT header, but valid main header; regenerating backup header from...

I do not have any spare places to put a drive, so I assume the best option would be to set the weight to 0 and then remove the OSD and drive once its empty?

Hi All What is the procedure to replace a drive in CEPH Proxmox Cluster, I have a drive which is dying. Thanks Mike

Ok intersting information, I assume the only option to change would be Restart=on-failure I'll do some reading to see how I do that. No option to detect segfault

Hi All I have a problem where OSDs are sefaulting, I've been asked to run a diagnostic command but its must be run while the OSD is down. So I need a way of stopping systemd from restarting segfaulted processes, or just not restarting them if they die. I've been googling but all the results I...

Ok that worked, but why did not it not work using the pveceph createosd ? root@pve:~# ceph-disk zap /dev/sdb 10+0 records in 10+0 records out 10485760 bytes (10 MB, 10 MiB) copied, 0.0983489 s, 107 MB/s /dev/sdb1: 4 bytes were erased at offset 0x00000000 (xfs): 58 46 53 42 10+0 records in 10+0...

I've tried everything I can think of to get the new OSD to be created and enable, but it does not appear even though I have zapped the drive rebooted then added it. Zeroed the drive for the first Gig of data. I have no idea what my next steps should be to add this drive.

I'm running CEPH and the lastest release from Proxmox and I'm still gettting major memory leak issues. The 12.2.2 release does not fix all the leaks. The OOM killer is killing an OSD at about a rate of one each 5 to 10 hours. I've not been able to find an example of how to reduce the cache to...

Hi I've been having an issue with the creation of OSD's, most times I can add a disk and it apears on the OSD page and ceph osd tree show the newly adding drive. But a number of times I've add the drive and I get something like the below which looks like its done but the drive is added to the...

So I started again from scratch and did not have the problem. I must have gotten the order of the steps wrong. I think the crush map was created before I had adjusted the 'crush chooseleaf type'.

Hi So I've built my Single Node Proxmox CEPH system and did not have a lot of issues the first time around. Other than some of my disks being a little old and giving errors. I wanted to start from scratch so I did not have the crund from me learning, but the second time around I simple can not...

Mine all matched, the serial numbers are all HEX. Seagate and WD Drives

The disks page for each node gives the model and serial number. Been working through this today with two drives which do not detect

Hi Is there an issue if I do a re-install of Proxmox after I've registered my support key ? I have been playing with CEPH with a single machine and want to start from scratch now that I have it worked out. Thanks Mike

Still given all that I can not take the production system online and the MDS is something which can be turned on and give me the storage I need. a VM NAS would not be running at boot time meaning the real servers would have trouble at boot time. ie mounting the NFS storage for ISOs and backup...

Because that would require me taking the whole production system offline. You need to justify you statement about glusterfs. I actually think sheepdog would be better than both as its got a lot less moving parts and supports NBD, iscsi, fuseFS and HTTP out of the box.

Hi All I would like to use CephFS for ISO files and the initial location for Backups before rsyncing them to a remote location. The issue I can not seem to get the steps worked out to actually create the file system in the ceph storage. Has anyone written a howto or just listed the steps...
