If the crash is not that of the disk but the computer itself, I may not be able to rebuild a similar hardware, so the question: is the BTRFS raid 1 mirror single disk readable (better bootable) on an other computer?
You mean if you lost one drive of two? If it's a true mirror, quite likely.
or none, if the computer (mobo, for example) fails, yoiu have two disks but no system
mdamdm disk are not, not without a small but non obvious change
What small change? provided you've set the md mirror up correctly, you can take a single disk, stick it in a new machine, and boot. The only problem is the boot may "fail" with "can't mount root" initially until you force the array to assemble degraded. At which point you can then add a new disk and rebuild the array.
this is what I mean as "non obvious". I can't connect it on an usb dock and read
I suspect that btrfs is just the same - with a disk missing the partition won't start up properly.
booting is not likely as the hardware has changed on this case, but reading it would be great. It's the "on the fly" part that makes me think that the disk may be readable thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
