[ovirt-devel] Re: Unexpected exception when trying to add a storage domain

On Thu, Jan 2, 2020 at 6:47 PM Dana Elfassy <delfassy(a)redhat.com&gt; wrote: This does sound like a healthy storage domain configuration. The way to create a storage domain is: In /etc/exports add entry like: $ cat /etc/exports /export/1 *(rw,async,anonuid=36,anongid=36) /export/2 *(rw,async,anonuid=36,anongid=36) Note: async is not safe for production, I'm using it to simulate a fast nfs server. You probably want to use sync which is the default. Reload nfs server configuration: # exportfs -r If you check the export you will see: # exportfs -v /export/1 <world>(async,wdelay,hide,no_subtree_check,anonuid=36,anongid=36,sec=sys,rw,secure,root_squash,no_all_squash) /export/2 <world>(async,wdelay,hide,no_subtree_check,anonuid=36,anongid=36,sec=sys,rw,secure,root_squash,no_all_squash) Then change the owner of the directory to vdsm:kvm (you many need to add a vdsm user on the nfs server) # chown -R vdsm:kvm /path/to/export On the host, the mount should look like: # mount | grep nfs1 nfs1:/export/2 on /rhev/data-center/mnt/nfs1:_export_2 type nfs4 (rw,relatime,vers=4.2,rsize=262144,wsize=262144,namlen=255,soft,nosharecache,proto=tcp,timeo=600,retrans=6,sec=sys,clientaddr=192.168.122.20,local_lock=none,addr=192.168.122.30) (I'm using NFS 4.2 which is much faster, you should use it too) # tree -pug /rhev/data-center/mnt/nfs1\:_export_2/ /rhev/data-center/mnt/nfs1:_export_2/ └── [drwxr-xr-x vdsm kvm ] 55255570-983a-4d82-907a-19b964abf7ed ├── [drwxr-xr-x vdsm kvm ] dom_md │ ├── [-rw-rw---- vdsm kvm ] ids │ ├── [-rw-rw---- vdsm kvm ] inbox │ ├── [-rw-rw---- vdsm kvm ] leases │ ├── [-rw-r--r-- vdsm kvm ] metadata │ ├── [-rw-rw---- vdsm kvm ] outbox │ └── [-rw-rw---- vdsm kvm ] xleases ├── [drwxr-xr-x vdsm kvm ] images │ ├── [drwxr-xr-x vdsm kvm ] 17b81130-f4a4-4764-ab5a-258a803c7706 │ │ ├── [-rw-rw---- vdsm kvm ] 66738f70-bb6c-4ce0-a98e-c7109d3b4275 │ │ ├── [-rw-rw---- vdsm kvm ] 66738f70-bb6c-4ce0-a98e-c7109d3b4275.lease │ │ └── [-rw-r--r-- vdsm kvm ] 66738f70-bb6c-4ce0-a98e-c7109d3b4275.meta │ ├── [drwxr-xr-x vdsm kvm ] 6fd5eafc-572b-4335-b59b-42282ba10464 │ │ ├── [-rw-rw---- vdsm kvm ] 46e25ec2-04ae-4829-b32d-972c1e15da09 │ │ ├── [-rw-rw---- vdsm kvm ] 46e25ec2-04ae-4829-b32d-972c1e15da09.lease │ │ └── [-rw-r--r-- vdsm kvm ] 46e25ec2-04ae-4829-b32d-972c1e15da09.meta │ ├── [drwxr-xr-x vdsm kvm ] b2cdc744-9992-4a97-8d80-37c40c5b8f84 │ │ ├── [-rw-rw---- vdsm kvm ] 12b58c9b-ccd7-4375-a0df-fc956075f313 │ │ ├── [-rw-rw---- vdsm kvm ] 12b58c9b-ccd7-4375-a0df-fc956075f313.lease │ │ └── [-rw-r--r-- vdsm kvm ] 12b58c9b-ccd7-4375-a0df-fc956075f313.meta │ └── [drwxr-xr-x vdsm kvm ] e95c50b2-d066-499b-9c58-6a479b50e515 │ ├── [-rw-rw---- vdsm kvm ] 69435001-9c25-41fd-85d3-7f7321a503e6 │ ├── [-rw-rw---- vdsm kvm ] 69435001-9c25-41fd-85d3-7f7321a503e6.lease │ └── [-rw-r--r-- vdsm kvm ] 69435001-9c25-41fd-85d3-7f7321a503e6.meta └── [drwxr-xr-x vdsm kvm ] master ├── [drwxr-xr-x vdsm kvm ] tasks └── [drwxr-xr-x vdsm kvm ] vms
