Re: [Gluster-devel] Relocating the namespace brick

I did see the same problem even after remounting the client. I moved the namespace files back to the original location, and things worked again -- evidently you can't just move the namespace files. The other thing I did was point the brick to a soft link. What is the correct procedure to move namespace files?

Do you see the Input/Output error even after remouting the client? the fuse
kernel modules sends this error when it encounters an unexpected inode
number change (caused by moving your namespace to a seperate disk).
Regarding the permission denied error, please check the permissions of the
parent directories where you have moved the namespace.
