Possible way to expand RAIDZ

[vlky]

HI All,

The problem I am always suffering in RAID solution is "volume (almost) full".

I created a FreeNAS system in a VM like the following. (Just initialized, no data yet)

raid5-001 (RAIDZ)
- 4 x 10GB

raid5-002 (RAIDZ)
- 4 x 20GB

================================================================

Questions

1) Is it possible to merge/stripe this 2 raidz OR or stripe or other drives together, such that I can see the single drive that which can be expanded by merging them up??

2) If question 1 concept is not possible, Shall I replace the existing disk in raid5-001 / raid5-001 with larger volume then grow it ???


I studied some articles about expanding the RAIDZ. "Seems" the first one is a possible way.


Thanks,
Victor LEE

This has been discussed thoroughly in my presentation. Please read through it(link in my sig).

There is NO way to merge multiple zpools together.

Thx cyberjock, one more question.

At last, I merged the mirror disks and raidz together. Does it safe enough? or any maintenance problem??
