Hi everyone.
I hava a problem with Debian Lenny server:
uname -a
Linux xxx 2.6.18-4-686-bigmem #1 SMP Wed Feb 21 17:30:22 UTC 2007 i686 GNU/Linux
This is an Etch system, unless it was dist upgraded to Lenny without
upgrading the kernel as well. Etch shipped with 2.6.18, Lenny with
2.6.26. Neither kernel version is going to want to play nice with 3TB
drives.
I connected two new disks to it:
Seagate Constellation ES.2, 3.5'', 3TB, SATA/600, 7200RPM, 64MB
BIOS sees them properly as 3TB drives, in shell I have:
brw-rw---- 1 root disk 8, 32 2011-08-29 19:46 /dev/sdc
brw-rw---- 1 root disk 8, 64 2011-08-29 19:46 /dev/sde
But fdisk doesn't recognize them and demsg shows errors for both:
sde : very big device. try to use READ CAPACITY(16).
sde : unsupported sector size -1548812288.
SCSI device sde: 0 512-byte hdwr sectors (0 MB)
sde: Write Protect is off
sde: Mode Sense: 00 3a 00 00
SCSI device sde: drive cache: write back
sd 4:0:0:0: Attached scsi disk sde
Has enyone had a similar problem? What is this READ CAPACITY? How can
I correct "unsupported sector size" and why it could occur?
I haven't "seen" an issue in this regard because I'm informed enough to
know a 4 year old kernel isn't going to work with 3TB drives, nor 3-4
year old user space disk tools. The error message above actually tells
you the disk is too big for the kernel driver.
Upgrade to Squeeze and the most recent Squeeze kernel. There is no
compatibility or other reason I know of that would force one to stay on
Lenny (or God forbid Etch, if you're still running it). Do
$ cat /etc/debian_version
to determine what dist version you're actually running.
