similar to: How to find out data alignment for LVM thin volume brick

Have you checked this page: https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/brick_configuration ? The alignment depends on the HW raid stripe unit size. Best Regards,Strahil Nikolov?

Dear Strahil, Thank you very much for pointing me to the RedHat documentation. I wasn't aware of it and it is much more detailed. I will have to read it carefully. Now as I have a single disk (no RAID) based on that documentation I understand that I should use a data alignment value of 256kB.

Hi all, I had centos 5.9 installed with one of its volumes (non-root) on LVM: ... /dev/vgapps/lvapps /opt/apps ext3 defaults 1 2 ... Then installed centos 6.4 on this servers but without exporting this volume (I wanted to reuse it). After that instead importing it I did: # pvcreate /dev/sddlmac # vgcreate vgapps /dev/sddlmac And then realised that I should have

I have a DAS w/ 6 750Gb and 6 1Tb discs I am setting up using Linux raid. The controller is a POS so each disc is exported as an R0 single volume. I used a parted and fdisk script to create 1 max size partition labeled as Linux Raid Autodetect and created the first r6 array w/ mdadm. I normally create and mark partitions as raid or lvm so people know what's going on. The first md array is

OK folks, I'm back at it again. Instead of taking my J4400 ( 24 x 1T disks) and making a big RAID60 out of it which Linux cannot make a filesystem on, I'm created 4 x RAID6 which each are 3.64T I then do : sfdisk /dev/sd{b,c,d,e} <<EOF ,,8e EOF to make a big LVM partition on each one. But then when I do : pvcreate /dev/sd{b,c,d,e}1 and then pvdisplay It shows each one as

How can I pass an array to a define? It''s not documented in the puppet language guide. I''ve got: define lvm::create_vg ( $pvdisks ) { exec { ''pvcreate'': command => "/sbin/pvcreate -yf $pvdisks", unless => "/sbin/pvdisplay $pvdisks", ... } } class someclass { lvm::create_vg {

'--no-degraded' flag in the first mdadm call inhibits the startup of array unless all expected drives are present. This will prevent starting arrays in degraded state. Second mdadm call (after LVM is scanned) will scan unused yet devices and make an attempt to run all found arrays even they are in degraded state. Two new tests are added. This fixes rhbz1527852. Here is boot-benchmark

I now how to expand a LVM by creating a new drive as described here: http://lists.centos.org/pipermail/centos/2007-February/032664.html, the steps are: # pvcreate /dev/sda3 # vgextend VolGroup00 /dev/sda3 Now, I want to know how to expand a LVM without create /dev/sda3? Suppose I have 2 GB free (unpartitioned) and LVM use /dev/sda2 (8 GB). How to make /dev/sda2 become 10 GB? Then resize LVM

Hi all. I'm using libvirt 1.2.6 I want to use lvm storage for my virtual machines. But i want to use new lvm2 feature - thin pool. How can i do that in libvirt? If libvirt can't create it via pool xml, does (and how) to use this setup under libvirt? -- Vasiliy Tolstov, e-mail: v.tolstov@selfip.ru jabber: vase@selfip.ru

Hi Sanoj, I copied over the quota.conf file from the affected volume (node 1) and opened it up with a hex editor but can not recognize anything really except for the first few header/version bytes. I have attached it within this mail (compressed with bzip2) as requested. Should I recreate them manually? there where around 10 of them. Or is there a hope of recovering these quotas? Regards, M. >

Mabi, We have fixed a couple of issues in the quota list path. Could you also please attach the quota.conf file (/var/lib/glusterd/vols/ patchy/quota.conf) (Ideally, the first few bytes would be ascii characters followed by 17 bytes per directory on which quota limit is set) Regards, Sanoj On Tue, Aug 1, 2017 at 1:36 PM, mabi <mabi at protonmail.ch> wrote: > I also just noticed quite

Thank you very much Sanoj, I ran your script once and it worked. I now have quotas again...

Hi mabi, This is a likely issue where the last gfid entry in the quota.conf file is stale (because the directory was deleted with quota limit on it being removed) (https://review.gluster.org/#/c/16507/) To fix the issue, we need to remove the last entry (last 17 bytes/ 16bytes based on quota version) in the file. Please use the below work around for the same until next upgrade. you only need to

Not a centos specific question here, but if anyone can save me from shooting myself in the foot would appreciate any pointers.... I have an older centos 4.7 box that I recently replaced with a newer one running centos 5.3. I'd like to add the hard disk from the older one to the newer one before I scrap it for good. I don't care about the data on it, would just like the extra drive

I also just noticed quite a few of the following warning messages in the quotad.log log file: [2017-08-01 07:59:27.834202] W [MSGID: 108027] [afr-common.c:2496:afr_discover_done] 0-myvolume-replicate-0: no read subvols for (null) > -------- Original Message -------- > Subject: [Gluster-users] Quotas not working after adding arbiter brick to replica 2 > Local Time: August 1, 2017 8:49 AM

I've replaced disks in a hardware RAID 1 with larger disks and enlarged the array. Now I have to find a way to tell LVM about the extra space. It seems there are two ways: 1. delete partition with fdisk and recreate a larger one. This is obviously a bit tricky if you do not want to lose data, I haven't investigated further yet. 2. create another partition on the disk, pvcreate another

I have a laptop that I put centos 7 on and I started out with a 30gig partition.? I resized the other part of the disk to allow more space for centos.? I then created an unformated partition in the available space,? ran pvcreate /dev/sda4 vgextend lvname /dev/sda4 lvextend -L 184.46G /dev/lvname/root but when I run: sudo resize2fs /dev/lvname/root I get: resize2fs: Bad magic

I tried to re-create manually my quotas but not even that works now. Running the "limit-usage" command as showed below returns success: $ sudo gluster volume quota myvolume limit-usage /userdirectory 50GB volume quota : success but when I list the quotas using "list" nothing appears. What can I do to fix that issue with the quotas? > -------- Original Message -------- >

Hello, As you might have read in my previous post on the mailing list I have added an arbiter node to my GlusterFS 3.8.11 replica 2 volume. After some healing issues and help of Ravi that could get fixed but now I just noticed that my quotas are all gone. When I run the following command: glusterfs volume quota myvolume list There is no output... In the /var/log/glusterfs/quotad.log I can see the
