After running ceph on XFS for some time, I decided to try btrfs again. Performance with the current "for-linux-min" branch and big metadata is much better. The only problem (?) I''m still seeing is a warning that seems to occur from time to time: [87703.784552] ------------[ cut here ]------------ [87703.789759] WARNING: at fs/btrfs/inode.c:2103

We''ve been seeing warnings coming out of the orphan commit stuff forever from ceph. Turns out it''s because we''re racing with checking if the orphan block reserve is set, because we clear it outside of the spin_lock. So leave the normal fastpath checks where they are, but take the spin_lock and _recheck_ to make sure we haven''t had an orphan block rsv added in

Hi, I'm a sys admin and currently working for a french hosting company. We provide DNS services to our customers and at the moment we are using BIND on Debian servers. BIND is a good software but we don't need a recursing DNS for our public DNS, and we needed better security than what BIND provides. So I made the suggestion to replace BIND by another DNS software. NSD appears to be the

Hi all, I am looking in to ceph and cephfs and in my head I am comparing with gluster. The way I have been running gluster over the years is either a replicated or replicated-distributed clusters. The small setup we have had has been a replicated cluster with one arbiter and two fileservers. These fileservers has been configured with RAID6 and that raid has been used as the brick. If disaster

Big raid isn't great as bricks. If the array does fail, the larger brick means much longer heal times. My main question I ask when evaluating storage solutions is, "what happens when it fails?" With ceph, if the placement database is corrupted, all your data is lost (happened to my employer, once, losing 5PB of customer data). With Gluster, it's just files on disks, easily

Good day everyone, I want to use the Gram-Charlier series expansion to model some data. To do that, I need functions to: 1) Calculate 'n' moments from given data 2) Transform 'n' moments to 'n' central moments, or 3) Transform 'n' moments to 'n' cumulants 4) Calculate a number of Hermite polynomials Are there R-functions to do any of the above?

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

Greetings all! I am in the process of deploying a POC around SAMBA and CEPH. I'm having some trouble locating concise instructions on how to get them to work together (without having to mount CEPH to the computer first and then exporting that mount via SAMBA). Right now, my stopper is trying to locate ceph.so for x64 CentOS 6.5. [2014/02/26 15:05:23.923617, 0]

Good day everyone, I want to assess the error when fitting a Gram-Charlier CDF to some data 'ws', that is, I want to calculate: Err = |ecdf(ws) - GCh_ser(ws)| The problem is, I cannot get the F(x) values from the ecdf. 'Summary(ecdf())' returns some of the x-axis values, but how do you get the F(x) values? Thank you for any help you can provide. Regards, Augusto

TLDR: Why is virsh migrate --persistent --live domain qemu+ssh://root@host/system --xml domain.ceph.xml not persistent and what could i do about it? Hi, after years of beeing pleased with local storage and migrating the complete storage from one host to another, it was time for ceph. After setting up a cluster and testing it, its time now for moving a lot of VMs on that type of storage, without

Hi, I'm trying to build an active/active virtualization cluster using a Ceph RBD as backing for each libvirt-managed LXC. I know live migration for LXC isn't yet possible, but I'd like to build my infrastructure as if it were. That is, I would like to be sure proper locking is in place for live migrations to someday take place. In other words, I'm building things as if I were

Hi everybody, my background: I'm doing Xen since 10++ years, many years with DRBD for high availability, since some time I'm using preferable GlusterFS with FUSE as replicated storage, where I place the image-files for the vms. In my current project we started (successfully) with Xen/GlusterFS too, but because the provider, where we placed the servers, uses widely CEPH, we decided to

Dear developement team, I want to share a massive storage casted with Ceph by samba with windows workstations. All works well. My problem so is that in windows the ceph storage size statistics are wrong. Instead of seeing a 44TB hard drive I see a 176GB hard drive. Under linux that issue doesn't show. The size are properly reported. I investigated around and it seems that the problem
