@poke Not all partitioning tools support resizing (most prominently fdisk does not), but all support deleting and recreating, which creates identical results.

| Jun 21, 2018 at 20:07 | comment | added | damaltor | So, after waiting for the resync on both disks everything is working fine now again. the partition is now shrinked, and i made a new one behind it. thanks for helping me! | |
| Jun 21, 2018 at 15:07 | comment | added | damaltor | The first resync is done. i have now changed the size of the second partition, which then also got kicked out of the raid, so i added it back in and they are syncing back up now... again. i am pretty sure that there would be a faster way, but this seems to do the trick. will come back after re-expanding the md and the filesystem afterwards. | |
| Jun 21, 2018 at 12:35 | comment | added | damaltor | I did so now, i deleted and made the partition new. after reboot, the device was flagged as removed from the raid, so i re-added it. syncing back up now, will update on progress in the comments here. | |
| Jun 20, 2018 at 21:52 | comment | added | Eugen Rieck | I definitly mean not removing it from the RAID - just changing the partition size, so that after the reboot the recreated partition with the existing RAID data is used. Superblock 1.2 should be fine. | |

| Jun 20, 2018 at 20:06 | comment | added | damaltor | Just to make sure, you mean deleting/adding the partition AFTER removing it from the raid? | |
