Hello,
Have a question regarding upgrade process.
In short.. i screwed myself during my first build.. and now i am paying the price :)
I currently have a RAIDZ1 of 3x 3tb disks, and it is about 81% full, i am now getting alerts / warnings about capacity. After reviewing my options i would like some input from the community on how to proceed and get some tips / advice.
option 1) replace each disk one at a time with larger (4 or 5 TB disks) .. this scares the hell out of me, as during the re silvering process .. i am opening my self up to a RAID0 like issues where any one disk failure during resilver means total loss of data.. :p
option 2) purchase 4 new disks and build a raidz2 config, and move everything over from raidz1 array.. this will cost me cash for new PSU that has enough sata power connectors .. and a HDD bay for the 5.25" bays in the front of the pc case to accommodate the extra disk that i do not have room for in the pc case..
option 3) purchase 3x 3tb disks and build new vdev and add to existing zpool .. however i will be setting myself up for failure again when 1 disk dies and during re silver process i will have high chance of failure ..
Question is.. I dont hear too many horror stories of people resilvering raidz1 resulting in total loss of data,..but even the though spooks me.. I understand option 2 is the best as i am resolving an issue of using raidz1 .. however it will cost me the most $$$.. Are there any other options or have i missunderstood my above options in anyway?? any help / input / ideas is MUCH appreciated.. thanks!!
