Create the lvm (this is where you can do things like setting up ssd cache as well if you want)

Wouldn't he want a raid 1 for the SSD Cache too though? Just in case a drive fails

If the data has any value, you don't do RAID 0 anyway. If speed is important, then adding fast cache drives makes a lot of sense, and is one reason to use RAID 0 (speed of access to ephemeral data). If the single cache drive fails, it just falls back to functioning without a cache.

I read that if there is data loaded in the failed drives (ala memory) that data is lost. Is that not the case?

Yes. This is why you don't load valuable data on a RAID0, ever.

Well yeah for sure, but I mean specifically the cache

MOst systems require RAID 1 for cache.

Apparently I'll need to take a look at the caching options for LVM again, didn't think it mattered.

@gilberto said in raid partition 0:

Excuse my ignorance. Now I was installing x2go. If I partition the hdd in raid 0 I also need to rebuild the operating system or just x2go. thank you.

To reiterate: Any time you are reconfiguring an array, you lose everything on the array.

If you want to keep the data, you must back the data up to a separate medium and restore it once you are done configuring the array.

All fixed. Did a full update, then had to modify the /root/.profile file from this line...

mesg n || true

To this line...

tty -s && mesg n || true
