I have install and configure on two server centos8 glusterfs in replica mode in this manner: dnf install centos-release-gluster -y dnf install glusterfs-server glusterfs glusterfs-fuse -y systemctl enable --now glusterd gluster peer probe virt1 gluster peer status sh creavolume.sh gfsvol1 301G /gfsvol1 xfs # NOTE: this is a my shell script to create fs on lvm mkdir

Hi, I am trying to remove a brick, from a server which is no longer part of the gluster pool, but I keep running into errors for which I cannot find answers on google. [root at virt2 ~]# gluster peer status Number of Peers: 3 Hostname: srv1 Uuid: 2bed7e51-430f-49f5-afbc-06f8cec9baeb State: Peer in Cluster (Disconnected) Hostname: srv3 Uuid: 0e78793c-deca-4e3b-a36f-2333c8f91825 State: Peer in

The systemd glusterd.service unit modify do not resolve my problem The solution is mount the glusterfs volume with this line into /etc/fstab: virt2:/gfsvol2 /virt-gfs glusterfs defaults,_netdev,noauto,x-systemd.automount,x-systemd.device-timeout=20,x-systemd.requires=glusterd.service 0 0 run systemctl daemon-reload and run this for mount the volume systemctl restart virt\\x2dgfs.mount

Tracing down some things to add in validators and I''ve run across something that kinda bothers me... In order to implement validators you have to override the clone method. The directors seems to be set up to specifically handle this situation. However, whenever C++ calls back to the object''s methods the swig_get_up function is returning false. It seems like swig_up

Chandler et al, I have been playing with the new PM pipeline, being particularly interested in how it can handle devirtualization. Now, I discovered what I believe is a "regression" vs old PM on a rather simple one-translation-unit testcase. clang is able to devirtualize it with -O3 and fails to do so with -fexperimental-new-pass-manager added. It looks like a pipeline issue,

Yes, this looks broken in the new PM. The DevirtSCCRepeatedPass::run method first scans the functions in the SCC to collect value handles for indirect calls, runs the CGSCC pass pipeline and then checks if any of the call value handles now point to a direct call, in which case it runs the pipeline again (which should inline the devirtualized call) . The problem is scanning the initial SCC for

Hi, I have the following volume: Volume Name: virt_images Type: Replicate Volume ID: 9f3c8273-4d9d-4af2-a4e7-4cb4a51e3594 Status: Started Snapshot Count: 2 Number of Bricks: 1 x (2 + 1) = 3 Transport-type: tcp Bricks: Brick1: virt3:/data/virt_images/brick Brick2: virt2:/data/virt_images/brick Brick3: printserver:/data/virt_images/brick (arbiter) Options Reconfigured: features.quota-deem-statfs:

Hey, Can you give us the volume info output for this volume? Why are you not able to get the xattrs from arbiter brick? It is the same way as you do it on data bricks. The changelog xattrs are named trusted.afr.virt_images-client-{1,2,3} in the getxattr outputs you have provided. Did you do a remove-brick and add-brick any time? Otherwise it will be trusted.afr.virt_images-client-{0,1,2} usually.

Here is the process for resolving split brain on replica 2: https://access.redhat.com/documentation/en-US/Red_Hat_Storage/2.1/html/Administration_Guide/Recovering_from_File_Split-brain.html It should be pretty much the same for replica 3, you change the xattrs with something like: # setfattr -n trusted.afr.vol-client-0 -v 0x000000000000000100000000 /gfs/brick-b/a When I try to decide which

In an effort to get a better understanding of Crossbow I decided to create some vnics for use between a couple of Solarsi 10 branded zones. I was quite surprised that when I went to verify the setup within zonecfg I got the following error. zonecfg:virt1> verify Error: solaris10 zones do not currently support exclusive ip-type stacks virt1: Brand-specific error Is this a feature that is

Is there a guide, or some suggestions for what filesystem to use for VM storage? I chose the standard ext3 on CentOS but I'm wondering if it makes more sense to look at ext4 or XFS for performance reasons? Does anyone tweak the ext3 journaling options for libvirt to speed things up? What about NFS export/mount options? What do your fstab mount lines look like? Is there a better

We have a Windows 2003 fileserver here on a domain. I've been mounting it via Linux for a couple years now. Some time in the last three months it stopped working. Perhaps some patch was applied that broke things? I have no idea what's causing it but I always get a permission denied error message. root@snikt(/mnt) :mount q-drive/ mount error 13 = Permission denied Refer to the

Hi Karthik, Thanks for the info. Maybe the documentation should be updated to explain the different AFR versions, I know I was confused. Also, when looking at the changelogs from my three bricks before fixing: Brick 1: trusted.afr.virt_images-client-1=0x000002280000000000000000 trusted.afr.virt_images-client-3=0x000000000000000000000000 Brick 2:
