I've been using ZoL for more than a year and now comes the time I NEED
But I am wondering what is the correct or best way to replace a dying,
but still working drive.
I am running Fedora 14 64 Bit and manually compiled ZoL 0.6.0-rc11
(planning to move to Ubuntu 12.04.2 LTS)
I did a few attempts I added the new drive to the pool with *zpool -f
And attempts to use replace (before and after it was added to the pool)
Latest situation (zpool status):
* pool: raid-z*
* state: ONLINE*
* scan: resilvered 4K in 0h0m with 0 errors on Fri Aug 9 17:09:13 2013*
* NAME STATE READ WRITE CKSUM*
* raid-z ONLINE 0 0 0*
* raidz2-0 ONLINE 0 0 0*
* sda ONLINE 0 0 0*
* sdb ONLINE 0 0 0*
* sdc ONLINE 0 0 0*
* sdd ONLINE 0 0 0*
* sdg ONLINE 0 0 0*
* ata-ST9500420AS_5VJ848CC ONLINE 0 0 0*
* sdk ONLINE 0 0 0*
*errors: No known data errors*
I know that drives sdb and sdd have many relocated block, so they are
likely to fail soon. Still gives me enough redundancy.
I am also wondering if the new disk sdk will be filled with data outside
the raid as a RAID0 combination of the raidz2-0 pool and sdk? Which I
obviously do not want!!!
So what is the correct procedure to replace the for example sdb ?
Sorry for maybe asking this very stupid questions.
