comment smartctl or hddtemp for xvda
My real problem is remote server reboots with no evidence I can see as to why. Following the advice at a serverfault article about precisely that, I was trying to check HDD temp. And I've gotten useful advice, which is to check with the hosting company if other machines sharing the same disks that I'm using are crashing, so thanks to @MadHatter

Fair enough -- so if I want to know if a temperature problem with my disks is the source of (apparently) random crashes, I'm out of luck?

I have succeeded in doing this.I largely worked from howtoforge.com/…, with appropriate minor changes for Debian, for raid10 and for an existing RAID in place. Details on request

comment Convert Raid 1 to Raid 10 with no new disks
Sounds simple, indeed, but, where do you stand to do step 3 "create the new array"? I'm running remotely, I can't boot and run 'in' e.g. a USB-self-contained distro.

comment Convert Raid 1 to Raid 10 with no new disks
Wikipedia's Non-standard RAID levels article illustrates several 2-drive RAID-10 layouts, and claims performance gains for the 'far' layout "This offers striping performance on a mirrored set of only 2 drives."

@Stefan, My reasoning was simply that Raid-0 is good, because striping gives efficiency gains. Raid-1 is good, because duplication gives some hope of recovery after failure. So 0+1 makes sense -- it's a recoverable efficient configuration.
