Failed to partition the selected disk [SOLVED]

Postby dargaud » 2018-04-27 06:59

Hello, hello,
I normally use Ubuntu or CentOS, but I need to install the latest Debian on a server. I've done that once before (8.5) and besides a nonfree driver issue, I didn't run into issues. But here: impossible.

I've put the nonfree 9.4 ISO on a USB key, I boot and start the install process. When comes time for the partitioning, I select the entire disk (a hardware RAID1 of 2 SSDs, 250Gb) and I get:
Failed to Partition the selected disk - This Probably happened because the selected disk or free space is too small to be automatically partitioned

I tried also in manual, same thing (with a similar but different message sometimes): impossible.

I tried that same ISO in a VM and I have no problem installing the system on a virtual disk.

I also booted my server with a debian liveCD and had no problem doing a quick and dirty partition of my SSDs manually using fdisk, fsck, mounting it and using it.

EDIT: a few extra info: the SSDs in the RAID1 are 240Gb Dell Perc H730 Adp. If I try to install on a RAID5 3Tb (normally meant for data), the installer proceeds normally.

So what is going on, why is the installer refusing my disk ?
Thanks

Have you re-accomplished RAID setup on the SSD's by clearing the partition tables and creating new raid partitions?
Nobody would ever ask questions If everyone possessed encyclopedic knowledge of the man pages.

Yes I have.
As a test I installed the latest (today's) Ubuntu and the whole install was done in 5 minutes, so I'm gonna use that instead. So I guess the problem is solved... in a way !
