Hi there, |
| 2 |
|
| 3 |
I have a weird harddisk detection problem which rises the questio: what does |
| 4 |
the gentoo-kernel make differently than the ubuntu kernel? |
| 5 |
|
| 6 |
The system in question has 2 identical SSDs (Kingston SV300S3 60GB) and two |
| 7 |
identical HDDs (older Maxtor7V300F0 300GB) , all connected to SATA/AHCI ports; |
| 8 |
the HDDs are combined to a LVM-raid1 volume. SATA controller is a onboard SB7x |
| 9 |
on an Asus M3A78 mainboard in AHCI mode. |
| 10 |
|
| 11 |
Only one of the two SSDs is attached at the same time to the system, the other |
| 12 |
one is disconnected. One contains a gentoo installation (just updated |
| 13 |
yesterday), the other one an Ubuntu LTS 20.04. This allows dual-.boot by |
| 14 |
switching connection cables. |
| 15 |
|
| 16 |
When I connect the gentoo-SSD and boot it, BIOS finds all HDDs and the SSD, and |
| 17 |
starts booting; but gentoo does not recognize at least one of the HDDs (/dev/ |
| 18 |
sdc missing, dmesg shows link down on Sata-Interface |
| 19 |
. Going back to the bios shows that even BIOS does not recognize the disk |
| 20 |
anymore. A full powercycle (pressing reset button is not sufficent) to make BIOS |
| 21 |
to recognize the disks again. |
| 22 |
|
| 23 |
Doing the same with the Ubuntu-Disk works absolutely fine, all HDDs are |
| 24 |
recognized and the raid is working fine, not a single time that one of the |
| 25 |
disks was not recognized. |
| 26 |
|
| 27 |
Without the Ubuntu observation I'd say its a hardware problem and the old HDDs |
| 28 |
are simply beyond their age, but why are they working in ubuntu and not in |
| 29 |
gentoo? And what is it doing with BIOS/Harddisk that even Bios does not find it |
| 30 |
anymore? I need a full powercycle to make bios find it again. This indicates a |
| 31 |
gentoo kernel problem, and I have no idea where to start looking, and AFAIK |
| 32 |
there's nothing much to configure a SATA/AHCI drive. |
| 33 |
|
| 34 |
Any ideas? |
| 35 |
|
| 36 |
Thanks |
