This I am still trying to do, the first pass copied all 350G of /home
but went to the wrong drive, and I had mounted the drive by its
label.
It is now /dev/sdh and all labels above it are now wrong. Crazy.
These SSD's all have an OTP serial number. I am tempted to use that
serial number as a label _I_ can control. And according to gparted,
labels do not survive being incorporated into a raid as the raid is
all labeled with hostname : partition number. So there really is no
way in linux to define a drive that is that drive forever. Unreal...
Interesting to see in how many differents ways you can use the
term "label". BTW I have no idea what an "OTP serial number" is.
OTP=One Time Pad, never to be used again.
I too can lookup acronyms with ease. I asked about "OTP serial number",
not "OTP" serial number.
I moved the data cable to where I knew I could find it again, as one
of 5 drives attached to the 16 port card,
No idea what that means.
and on reboot it shows up in
an lsblk list as:
root@coyote:~# lsblk
[ … table showing five Samsungs, five Gigastones, and two
other items, perhaps printer (confirmed later) and camera … ]
Now confirmed by looking at all 5 with gparted, there are only 3
unique serial numbers:
I don't see any parted output.
cuz it doesn't want to be copy/pasted.
root@coyote:~# ls /dev/disk/by-id
ls -1 would at least sort out this mess, but more useful would be ls -l
or for j in /dev/disk/by-id/* ; do printf '%s\t%s\n' "$(realpath
"$j")" "$j" ; done
as you could then see what the symlinks point to, which after all
is their raison d'être.
Thanks for that composition: but it will be word wrapped:
root@coyote:~# for j in /dev/disk/by-id/* ; do printf '%s\t%s\n'
"$(realpath "$j")" "$j" ; done

but like I wrote, 2 pairs with identical "serial numbers", so the
assunption is that the last one overwrites the first on by udev, when
IMO it should be yelling about the duplicats.
Extracting:
ata-Gigastone_SSD_GST02TBG221146
ata-Gigastone_SSD_GSTD02TB230102
ata-Gigastone_SSD_GSTG02TB230206
these devices appear to have normal serial numbers. Do they bear
any other indication, like engravings or stickers? If not, I would,
in turn, plug each one in, read the serial number from its symlink,
and write on it with a marker. While doing that, you could also
run smartctl.
only 3 unique serial numbers!!!!!!
udev when finding that situation should scream from the rooftops!!
not silently overwrite an entry in the by-id that its already made.
If you say so. I never had any problem with udev when I had
three identical USB sticks with the "serial" number
ID_SERIAL=SMI_USB_DISK-0:0
I scratched distinguishing letter on them, and watched xconsole for
the drive letter whenever I plugged one in. At 8GB a piece, the
largest I had at the time, they were very useful. And they didn't
cost me a penny as they were giveaways.
HTH do I fix that?
can tune2fs edit a serial number? no.
can the UUID be rendered read-only, no.
gparted and similar can change the UUID by a click of the mouse.
I'm officially screwed and I have had them too long to return them now.
You need to find out, in turn, which ones work, and that goes for
both the SSDs and wherever you plug them in. You can make little
progress at all without distinguishing them, as you have already
shown by copying data to who knows where.
Which occurred before I knew about the dups. Now you seem intent on
calling me a liar, which I do not intentionally do. I have now LABELed
the drives but the only way I can prove it to you ts seems would be to
take screen snapshots x5 of them, and one of those would be too big for
the server.
Now, I have spent since around 08:30 my time this morning trying to
backup this raid with around 350G of data on it, to one of those 2T
gigastones but have lost the whole system because (apparently) rsync has
a huge memory leak, the system is fine, until I start as root
"rsync -av --bwlimit=3m --fsync /home/ /mnt/homevol"
which is where /dev/sdh1 is mounted. watch the system with htop, memory
bar goes to full scale in tan, in 10 to 15 minutes and into swap 500
kilobytes in another 5 if OOM hasn't killed htop, the OOM daemon starts
killing things, and is not the least fussy what.
I have tried it without the --bwlimit and --fsync but that just bombs
the system faster. I thought I was overpower the write speed of the
drive but slowing it to garden slug speeds still eats memory and the
system gets killed. 38G of 350G is as far as I'm managed to get copied
from 08:30 to 17:35. If that commandline above it correct, then as
AFAIAC rsync is busted. The memory gauge bar is in 3 colors, green at
the left is I prsume allocated mamory, next is red (cache maybe) and
then tan or orange. The man page does not define what color signifies
which but run rsync, it runs to the right end of the bar in orange/tan,
then into swap and the system slowly dies.
I'm not a great user of rsync, use mc more often than not. I just have
seen it take up from where the reset or power switch was used to reboot
cuz the control of the system had been killed. So the command line
above might be the problem. You tell me, please.
That could even explain why my first run of rsync worked fine but went
to a drive that was NOT mounted. And it was mounted by LABEL= The
only one of those 5 SSD's I had labeled at that time.
You haven't shown any evidence of such LABELling, and most of your
anecdotal narratives don't give much confidence for us to really
know what was actually done. But to be fair, anything could
happen if the hardware is not working properly.
I give up, lets see if a gparted screenshot comes thru. there was one
attached when I hit send.
Cheers,
David.
whoppie-ding, it worked. call me a liar again.
