Can anyone give me a clue where the naming of disk devices is defined?
The links in /dev/disk/by-id/ are maintained by the kernel and are derivated from the device ID the manufacturer defined at production time.
For network interfaces you have: /etc/udev/rules.d/70-persistent-net.rules
Is there an equivalent for sata-drives? On my file server, i had five drives, the original sda (where i boot from and contained the 11.3) and four others in softread-10.
Unfortunately, two weeks ago, my sda "expired", so i bought a new one. As a precaution i disconnected the all data-drives during the installation of 12.2. After completion, i powered down the machine, connected the data drives, powered up and after a "vgchange -ay" the secondary volumegroup was detected and i could manually mount all LV's again, and i started recovering.
Alas, after last nights reboot, the disks holding the OS now appears as "SDE" instead of "SDA", and my secondary volume-group remains invisible.
I guess this is caused by two independent issues. Have you modified anything in between the reboots? Either on the BIOS or on the cabeling level? Connecting SATA disks to different SATA ports might result in a changed order.
I had the impression that suse was doing the mount by UUID by default. but obviously i'm mistaken?
The default is mount by UUID. Check your /etc/fstab and you'll know. Cheers, Lars -- Lars Müller [ˈlaː(r)z ˈmʏlɐ] Samba Team + SUSE Labs SUSE Linux, Maxfeldstraße 5, 90409 Nürnberg, Germany
