 |
|
HI all, I've cloned my gentoo from sdb2 to sdb1, I've changed boot flags, I've lauched grub-mkconfig but gentoo start always from sdb2. I noticed that sdb1 and sdb2 have the same UUID
| Code: | ┌─[root@hptoo] - [/home/martoo] - [2017-10-06 11:36:30]
└─[0] <> blkid
/dev/sdb2: UUID="254cbe70-ff7d-47e4-9a6a-e6a771ba66eb" TYPE="ext4" PARTUUID="565613c9-02"
/dev/sda1: LABEL="SYSTEM" UUID="D224-521F" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="06a19107-706c-4700-8087-1d6a2a5334ff"
/dev/sda6: UUID="1d596c35-2e8d-4796-9a19-83770e497450" TYPE="swap" PARTUUID="69cc3fed-50ec-4be0-a39e-fc7971ce0ef3"
/dev/sda7: UUID="5849d6b6-3410-41d1-a1ec-a3cb9f78a9e8" TYPE="ext4" PARTUUID="aa40d595-9255-4085-b481-7071fe3cb20e"
/dev/sdb1: UUID="254cbe70-ff7d-47e4-9a6a-e6a771ba66eb" TYPE="ext4" PARTUUID="565613c9-01" |
then I've modified fstab with /dev/sd* instead that UUID
This is my grub.cfg

| Hi, sda8 is a partition created by freebsd installer. But the system works, I don't think this is the problem, or am I wrong? |

https://bbs.archlinux.org/viewtopic.php?id=215541 provides info on changing PARTUUID and UUID
Having two partitions with the same PARTUUID and PARTLABEL which each contain filesystems with the same UUID is not a good idea.

Still recommend making new UUID for filesystem and PARTUUID for filesystem/partition /dev/sdb1 or /dev/sdb2. grub does not much care about fstab.

I would create both a new UUID and a new PARTUUID and then update/edit grub.cfg
