Is this only with Mageia 6 VBox host? Or with both Mga6 and mga5 host? Keywords:

NEEDINFO That's normal If you change/add/remove physical disks so the physical order changes, you need to adapt accordingly. Linux adapts automatically if you do uuid (like we do by default) or label mounts ... So if you used /dev/sd* in vbox config, so it will need updating You could have used /dev/disk/by-uuid/* or /dev/disk/by-label/* to get a mount Point that auto-adapts Status:

RESOLVED Note that this was opened as an FYI -- to provide info for anyone else running into this issue. @ Marja The version is immaterial (currently running 6 as guest on 5.1 host. The issue is that adding an SSD into a 2 HD laptop changed the storage order and VB storage config needs to be adjusted. @ Thomas Mostly true. The difficulty, and the reason for my FYI, is that host moved the 2nd HD, then many days later, firing up VB "looked" like it did before (sda & sdb); only sdb was totally invalid with no clue why[1] until I finally figured out that the vmdk was now wrong. Unfortunately, according to their latest manual, VBox 5.1.18 still does not support UUIDs for storage. Reported to Oracle at https://www.virtualbox.org/ticket/16622 as an enhancement request. [1] the installation screen even showed the correct partition scheme, apparently from the DIST-pt.vmdk file which added to the initial confusion. Resolution:
INVALID =>
FIXED Update: Where the VBox UserManual section 9.9.1.2 reads "/dev/sda", the disk specification can instead be specified as "/dev/disk/by-id/<ID>" where ID can be determined with "ls -l /dev/disk/by-id". /dev/disk/by-uuid/* and /dev/disk/by-label/* (specific to partitions) are not supported as of VB 5.1.18; so partitions can not yet be specified this way. |
This issue being filed to provide a clue for SSD users. Starting with a 2 HD Dell M6800, VB saw the drives as HD1 = sda & HD2 = sdb. Adding a Samsung EVO 250GB SSD drive caused Linux to assign drives as: HD1 = sda, SSD = sdb & HD2 = sdc My local Mageia Linux install repository resides on HD2p7. This physical source disk was originally defined in VBox's DIST[-pt].vmdk as sdb. After the SSD was installed, VB could no longer see the installation files because HD2(sdb) was now at sdc. Simply editing DIST.vmdk to change the only occurrence of sdb to sdc resolved the problem, allowing install to proceed. Note: VBox disk mappings differ from real HDs i.e.: Linux: HD1 = sda, SSD = sdb, HD2 = sdc VBox: sda = virtual disk file, sdb = sdb before SSD | sdc after SSD install.
