I have в pci raid controller, with two 250G drives. Configured this to work on ubuntu 11 в few years back. Have since forgotten much about the details of this configuration (i.e. программное обеспечение, хардвер, raid type) and have recently installed 14.04. On my 11 installation, I had в 500G mount. гm guessing it was raid0 or some other программное обеспечение configuration of the 2 disks.
How хан I get this existing pair of raid disks working again without erasing any of the восходит?

Наткнулся на dmraid
. Следующее вернуло мой lvm. По-видимому, у меня уже был LVM?
sudo dmraid -ay
RAID set "sil_ajajcfbibhah" was activated RAID set "sil_ajajcfbibhah1" was activated
sudo blkid
дал мне UUID
/dev/mapper/sil_ajajcfbibhah1: UUID="59b2e940-380c-4087-bd6a-50e9cc23ccfc" TYPE="xfs"
После этого я смог добавить запись в / etc / fstab [ 118]
UUID=59b2e940-380c-4087-bd6a-50e9cc23ccfc /media/storage xfs defualts 0 0
Надеюсь, что это может помочь другим.
