In the past I was doing:
blockdev --rereadpt /dev/sdX
and it usually worked on other controllers to reread the size visible
from "blockdev --getsize" or "blockdev --getsize64". One time I think it
even worked on exactly *that* controller... but it's not working now,
it's strange.
Is there a technique, or I am out of luck?
The machine should not be rebooted
I would even enter the size manually if possible: I know how many LBA
blocks are in that disk.
What dmesg output do you get when you do this?
with "this" I suppose you mean the blockdev --rereadpt?
This is the dmesg I get upon blockdev --rereadpt:
[508100.472337] sd 3:0:1:0: [sdr] 1465149168 512-byte hardware sectors
(750156 MB)
[508100.472376] sd 3:0:1:0: [sdr] Write Protect is off
[508100.472381] sd 3:0:1:0: [sdr] Mode Sense: 00 3a 00 00
[508100.472412] sd 3:0:1:0: [sdr] Write cache: enabled, read cache:
enabled, doesn't support DPO or FUA
[508100.472418] sdr: unknown partition table
It rereads the wrong size, i.e. the one of the old disk :-(
I am sure sdr is the correct disk, I even identified it by doing dd
if=/dev/sdr of=/dev/null and then looking at the activity led to confirm
it's the right drive. It should have read a size of 1TB.
Thanks for your help
