Hi Christophe
First of all, thank you for your help
I have done what you asked
I put the log on my dropbox here
https://www.dropbox.com/s/x627ip9h8tsic ... k.log?dl=0
but to help on the results, I also put pictures of the config in the disk manager
Originally this structure was done with three 500GB disks (disk 0,1,2)
As you can see the two first disks have 3 partitions, the 2 first partitions are actually operational to form a dual-boot and both OS are in mirror RAID.They are working without any problems
The last partitions on disk 0 and 1 and the fist partition on disk 2 created a volume named RAID-5_700 of ...700GiB which is the one I destroyed.
Disk 2 died, I replaced it by a bigger 1 terabyte disk. I rebuilt the volume RAID-5_700 and .... I suppressed the volume by error by acting on the new disk 2
By the way I have seen that you are french, so am I. As so I can continue in any languages of your preference. I guess english should be better on this international forum.
On the log, you probably will see that I scanned the disk 2 twice, which was also ...an error
Thank you again for your time
