The build jobs are separated like this
- /export/workspaces Mount point of shared disk
- /export/workspaces/workspace1 <- VM1 writes to this folder tree
- /export/workspaces/workspace2 <- VM2 writes to this folder tree
- ...
So the question is whether the ext3/ext4 file-system gets corrupted when each VM writes to different folder trees!? So this goes down to how the ext3/ext4 file-system works internally.
And if ext/3ext4 is not working, how about using another file-system which can cope with this scenario!?
