Hi folks
I had a 4 disk RAID 5 array which had a single EXT3 file system on it that housed all my shared folders.
I recently added a 5th drive to the array, and successfully reshaped the array overnight.
When I try to resize the file system through the GUI, and after clicking "do you really want to..." confirmation dialog box - nothing happens. The file system remains the same size.
I am OK on the CLI, and have a reasonable, but basic understanding of Linux systems and specifically RAID.
On doing a tonne of searching around (before posting here) I found a number of things to try but didn't make any progress.
I am not sure what sysinfo to post, so will include what I most commonly saw asked for. I would appreciate any guidance / help.
