Files created by one SDC not visible for other SDCs on the same volume
Hi,
I have three individual SDC servers. Have created a scaleio cluster which maps one volume to all three SDCs. Now, after mounting the volume to the three SDCs - when I create a single file in one of the SDCs, the other two SDCs do not see the same. Can you please advise what could be going wrong ? Or do I need to take any additional steps, to share the volume across the SDCs ?
Thanks.
On SDC1
[root@emcsdc1 /]# mount /dev/scinia /mnt/vol1
[root@emcsdc1 /]# cd /mnt/vol1
[root@emcsdc2 vol1]# vi test5.txt
On SDC2 (same behaviour on SDC3)
[root@emcsdc2 /]# mount /dev/scinia /mnt/vol1
[root@emcsdc2 vol1]# ls

I think you just format the volume with a non clustered file system like ntfs or ext 4.
If you want that all your server can access and write on the same volume you need a clustered file system (like cluster shared volume on windows) or ocfs/gfs on linux

Thank you Aglidic. Are there any references of gfs usage/configuration with scaleio ? How to set it up etc. Thanks!

Hum in that case you have to take the scaleIO like a normal array. So you just have to present the luns to all server and after follow a classical ocfs/gfs implementation like this:
