I hope you are doing well. I have been using OMV for quite a while now. A colleague kinda talked me through the installation process. I am an absolute newbie in terms of UBUNTU/UNIX, Terminal and Shell lines. However, i am doing my best to learn. OMV makes it a little bit easier as many functions (e.g. RAID Management) are already on board. Thanks to the GUI they are quite easy to handle.
The system is now running since three maybe four years. There are three drives installed:
1. SSD - on which OMV runs
2. 10TB HDD #1
3. 10TB HDD #2
Both HDDs are running in RAID 1 Mode. However, since last week HDD#1 keeps gaining bad sectors. To prevent data loss and also to learn how to do it, i require some help as i want to replace the "bad" HDD.
I would love to do it with the OMV GUI. By now i have read a lot about mdadm, however this might require too much shell knowledge which currently not have yet.
Could someone please be so kind and list the necessary steps to :
1. remove the 'bad' hdd from the software raid 1
2. prepare the new hdd (will be the same model and make - HGST 10TB Data Centre Storage)
3. Incorporate the new hdd to the system
4. restore software raid 1 on the new hdd (i would basically expect the system to just copy all the data until they are both synced)
I have used the search function of this forum - i stopped after page 9 as most of the problems seem to be with RAID5...
Many thanks in advance
