Hi, i see that i messed up "h" and "k" in my explanation of the fight over the link targets in /dev/disk/by-id. So another attempt:
sdh has a unique serial number GSTD02TB230102. Thus we see in https://lists.debian.org/debian-user/2024/01/msg00667.html these two links: /dev/sdh /dev/disk/by-id/ata-Gigastone_SSD_GSTD02TB230102 /dev/sdh1 /dev/disk/by-id/ata-Gigastone_SSD_GSTD02TB230102-part1 sdi and sdj share the serial number GST02TBG221146. So the concurrent attempts to create the links let only these two survive: /dev/sdi /dev/disk/by-id/ata-Gigastone_SSD_GST02TBG221146 /dev/sdj1 /dev/disk/by-id/ata-Gigastone_SSD_GST02TBG221146-part1 sdk and sdl share GSTG02TB230206. The survivors are: /dev/sdk /dev/disk/by-id/ata-Gigastone_SSD_GSTG02TB230206 /dev/sdk1 /dev/disk/by-id/ata-Gigastone_SSD_GSTG02TB230206-part1 The next system startup might yield other survivors. Have a nice day :) Thomas
