Re: [HPDD-discuss] OST deactivated but still objects being written to it?

Hi Nico, I Just saw your message. Even though I have it deactivated, something is still writing significantly. Hope you can help me understand this better. Even though new objects are not assigned can the disk usage increase for the existing objects? On the other hand, my migration script is not able to locate any files on the OST to move, which is odd. One thing I know is some files names are very odd, like may be 20-30 spaces in a file of length about at least 100 characters. Some users program is fanatic in file name creation and I have no control over it. Hope you can shed some more light. I am planning on running fsck to identify any issues with the ost.

Hi, temp. deactivated OSTs via 'lctl --device devno deactivate' will be marked as inactive. No new objects are assigned to the deactivated OST, but reads and writes of existing objects are still no problem.
