I have this *Let's see about ssd's* install on partition 3 of a 250gb tester (GPT table). It stopped booting (possibly after an update). Some start job is not completing. see attached.

how many disks are in this machine?

#1 2tb normal battlestar wd #2 250gb samsung ssd #3 unbootable 2 tb backup wd #4 unbootable 2 tb backup wd (green POS on death row) #5 unbootable 500 gb oldie wd if I wanna boot the ssd, i pull #1 if I wanna boot the primary i pull the ssd #3 is always plugged-in the others i plug/pull according to anticipated need {I don't do raid & I use only dev-id} slot #5 is really unusable, it serves as a shelf mostly because bios setup assigns #5 & #6 to IDE so as to protect DVD boots. I haven't yet looked into working around this for lack of real need to. I'm still learning, I think if i leave #1 and #2 withj the ssd in then the ssd will boot, don't know why the ssd would preferentially show up a the boot disk I love this kind of storage, no internal fixed drives!

if I wanna boot the ssd, i pull #1

if I wanna boot the primary i pull the ssd

#3 is always plugged-in

this was WROOOOONG

Well, the photo you showed looks like you use devname (/dev/sda3) in fstab.

To ask the question is to answer it. Did I say I was experimenting with SSD? When I installed it there was no other drive plugged-in, so it showed up as partition-3 on /dev/sda. But then I forgot that if booting the ssd then the other drives could be plugged-in only after booting. It's the same story as when the first SATA's hit the street, if only one PATA was also plugged in then it had to become /dev/sde. I don't se why it has to be this way but it doesn't really matter because soon there may be no magnetic drives left at all just like there are no PATAs left today.

Try booting by-uuid or by-label, and it might work better / more reliable.

That's a non-starter for me, it may be more reliable in some ways but it's too many headaches for me as I use dd blatantly, all the time, to copy partitions :-) If dd ever becomes extinct I'll can computing ALTOGETHER! -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

No headaches here, where cloning is routine. It's a simple enough matter to update UUIDs and LABELs after cloning operations. I both boot and mount FOSS filesystems by LABEL as a matter of course, which is mentally much easier than by UUID or by ID. The labels make it simple enough to keep track of what's what when partition count is the normal-for-around-here count of upwards of a dozen, even as many as 63 on one disk. -- "The wise are known for their understanding, and pleasant words are persuasive."

That /shouldn't/ be a problem. Or rather it wouldn't be a problem for me, if I used DD to copy. Sometimes I use rsync. that's very useful when I'm face with my ~/MyPhotographs/ByYear and want to move part of the tree, say 2015, to a new partition. I can also use it with 'find' to do more specific filtering. I mention this as moving part of partition, splitting a partition, freeing up space, archiving, is more common for me, and I suspect a number of other people. that simply shuffling partitions. When I do need to copy a partition as a while, well I use LVM, remember :-) That has the ability to move a 'partition', or as LVM terms it, a Logical Volume (LV). Simply take a snapshot and copy that. heck, the snapshot only need to be as big as space used on the primary, so you can use this technique to shrink or grow a 'partition'! If you’re using the same size partitions you could use dd, or even xfs_copy if you’re using XFS. However if what you are doing is a "move", that is a copy/delete-the-original, migrating to a new physical drive, the 'pvmove' command can do that all in one go. But in the absence of LVM, simply using DD to copy, yes it copies the whole image, and with it the UUID and label information But so what? You can simply - and immediately, before you forget - relabel the new partition and set a new uuid The 'swaplabel' command can be used for this, do them both with one command: swaplabel -L NEWLABEL -U $(uuidgen) /dev/sdXXXnnn There are probably other ways, after all this is Linux and Larry's Dictum usually applies" "There's more than one way to do that". -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
