Gentoo install does not see /dev/sda1

fogpipe · 05-22-2012, 01:10 PM

I plan on putting everything on that one partition for / and already have a home partition which i plan on mounting after the install.

Cfdisk sees /dev/sda1 fine. That partition is already lilsted in cfdisk as xfs. Yet when i try to mount it, i get the error "no such file or dir /dev/sda1". i have no trouble mounting that partition when booted to my vector linux install. when booted to vector the mount command lists that partition as
/dev/sda1 on /test type xfs (rw)

Help. I havent had a gentoo install in years and im looking forward to it.

im using the latest amd64 minimal iso on a dual core pentium d.

EDIT: i just booted up the install routine and the error message from mount is:"special device /dev/sda1 does not exist"

Try /dev/sda instead of /dev/sda1.

i think mount requires that a specific partition be named. i tried mounting other partitions on /dev/sda and got the same error, despite /dev/sda being listed in /dev, and specifying the file type.

Let's see "parted -l" (as root) from both systems. Use [code] tags when replying.

Here is the output from parted when booted to vector:

Code:

[root@thor:test]$parted -l /dev/sda

Disk /dev/sda: 250GB

Retry/Ignore?

the listing for parted -l /dev/sda while booted to the gentoo install is identical except for the warning at the end.

Here is something interesting tho, while booted to vector:

Code:

[root@thor:m0rl0ck]$fdisk -l /dev/sda

Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders, total 488397168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x4b0c250a

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *          63    97659134    48829536    7  HPFS/NTFS/exFAT
/dev/sda2        97659135   488392064   195366465    5  Extended
/dev/sda5        97662976   222586879    62461952   83  Linux
/dev/sda6       222588928   478527487   127969280   83  Linux
/dev/sda7       478529536   488390655     4930560   82  Linux swap

so fdisk is seeing it as a windows partition while parted and cfdisk are seeing it as xfs. It did originally have XP on it.

That'll do it to you.
The partition (type) id is rarely used (as you can see from parted), but it is sometimes. Linux won't install to NTFS - I think it will to VFAT, but why .... ???.
Change it to Linux - can be done on the fly without harm, but personally I'd do it from the liveCD (i.e.unmounted).

Heres the update. I called it quits on installing gentoo and took it back up again earlier tonight. I installed gentoo chrooted from vector linux instead of booted to the cd and im currently using firefox Xforwarded over ssh from my old celeron machine on the gentoo install while XDM and all its dependencies emerge. I emerged just enough to get fluxbox going with startX.

The drive appears to have settled down but my gentoo install stops during the boot and asks me to specify a root device, i think i can fix that but it may become another topic. thanks for the help
