similar to: virsh not connecting to libvertd ?

Just found my issue. After I removed the cephfs mounts it worked! I will debug ceph. I assumed because I could touch files on mounted cephfs it was working. Now virsh list works! thanks jerry Lars Kellogg-Stedman > On Tue, Jun 06, 2023 at 04:56:38PM -0400, Jerry Buburuz wrote: >> Recently both virsh stopped talking to the libvirtd.

Hello Jack, yes, I imagine I'll have to do some work on tuning the block size on cephfs. Thanks for the advise. I knew that using mdbox, messages are not removed but I though that was true in sdbox too. Thanks again. We'll soon do benchmarks of sdbox vs mdbox over cephfs with bluestore backend. We'll have to do some some work on how to simulate user traffic, for writes and readings.

Hi, some time back we had similar discussions when we, as an email provider, discussed to move away from traditional NAS/NFS storage to Ceph. The problem with POSIX file systems and dovecot is that e.g. with mdbox only around ~20% of the IO operations are READ/WRITE, the rest are metadata IOs. You will not change this with using CephFS since it will basically behave the same way as e.g. NFS. We

Thanks Jack. That's good to know. It is definitely something to consider. In a distributed storage scenario we might build a dedicated pool for that and tune the pool as more capacity or performance is needed.

I have identical two hypervisors same operating system: Ubuntu 22.04.2 LTS Recently both virsh stopped talking to the libvirtd. Both stopped within a few days of each other. Currently if I run: virsh uri virsh version virsh list # virsh list ..nothing just hangs When I ran strace on these broken machines it get stuck at same spot: strace virsh list ...

I'm sending this message to both dovecot and ceph-users ML so please don't mind if something seems too obvious for you. Hi, I have a question for both dovecot and ceph lists and below I'll explain what's going on. Regarding dbox format (https://wiki2.dovecot.org/MailboxFormat/dbox), when using sdbox, a new file is stored for each email message. When using mdbox, multiple

Hello Using two file server with samba 4.12.6 running as a CTDB cluster and trying to share a specific path on a cephfs. After loading the config the ctdb log shows the following error: ctdb-eventd[248]: 50.samba: ERROR: samba directory "/plm" not available Here is my samba configuration: [global] clustering = Yes netbios name = FSCLUSTER realm = INT.EXAMPLE.COM registry

Hello Florent, How did you proceed with the upgrade? Did you follow the recommended steps guide to upgrade ceph? (mons first, then OSDs, then MDS) Did you interrupt dovecot before upgrading the MDS specially? Did you remount the filesystem? Did you upgrade the ceph client too? Give people the complete scene and someone might be able to help you. Ask on ceph-users list too. Regards, Webert

Hi list, we have migrated a single node Samba server from Ubuntu Trusty to a 3-node CTDB Cluster on Debian Bullseye with Sernet packages. Storage is CephFS. We are running Samba in Standalone Mode with LDAP Backend. Samba Version: sernet-samba 99:4.18.2-2debian11 I don't know if it is relevant here's how we have mounted CephFS on the samba nodes: (fstab):/samba /srv/samba ceph

Hi, I'm testing out ceph_vms vs a cephfs mount with a cifs export. I currently have 3 active ceph mds servers to maximise throughput and when I have configured a cephfs mount with a cifs export, I'm getting a reasonable benchmark results. However, when I tried some benchmarking with the ceph_vms module, I only got a 3rd of the comparable write throughput. I'm just wondering if
