When you boot with the new drive in place, what is its block
device? Is it /dev/sdb or some other device name?<br>
<br>
I understand from your email that your server will boot with the new
drive installed if you comment out the fstab entry which references
filesystems on /dev/sdb . If the new drive becomes /dev/sdb could
you boot up without sdb in fstab, and then while the server is up
you could format the drive the way that fstab expects, and then
uncomment the sdb lines in /etc/fstab, do 'mount -a' to mount them,
and then once you're sure everything is OK, then reboot the server
and it should come up normally. Did you try that?<br>
<br>
If the new drive simply won't become /dev/sdb and you need it to
become /dev/sdb then maybe you have a persistent block device name?
Maybe you could look for & edit udev configs to get rid of the
old sdb device config.

It seems like I had to do something like this once but it's been so
long I've forgotten the specifics. I know I have to edit udev
configs to make ethernet cards get the right ethX id.<br>

<div aria-label="Compose body"> I've run into a situation that
has me puzzled (& a little bit humbled, actually). I have
a server that started out with five drives, sda - sde (no
RAID, no LVM). The sde drive has been throwing alerts for a
few days, so I went in to the DC to replace it. The drives
are hot-swappable, so I didn't expect much problem - but when
I inserted the new drive, the server appeared to not detect it
- and started to generate alerts for the sdB drive as well.
(I'm sure that at least a couple of you can probably see where
this is going...)<br>

<div aria-label="Compose body"> After puzzling over the
problem for a little while, I found that the new drive had
(appropriated|been assigned to) the sdB slot, rather than sdE
like I had expected. At that point, I started trying to
collect info so that I could recreate the fstab file using
'mount-by-uuid' - but regardless of what configuration I try,
I can't seem to get the original sdB drive to reappear:<br>

anyone has any questions, I'll do my best to answer them.<br>
