ct1996 Posted September 6, 2018 Share Posted September 6, 2018 (edited) So after some googling I found johnnie blacks post about various formats for cache pool devices, raid0,raid1,jbod, etc I have a 128gb Ssd that I currently use for docker appdata only.. I transfer data too much/too fast to bother with enabling cache, and having it always be full, and whatever. So I bought a 500gb ssd to supplement and I want to add it to my array, and enable cache. Do I have to lose the data thats currently on my 128gb? I obviously can back it up (it already is), but maybe was hoping I didnt have to anyways, is add drive to cache pool, let it format/wipe the new drive (not the old 128gb!!) , and then set the options in both drives to the commands specified by johnnie black, the correct procedure? thanks folks Edited September 7, 2018 by ct1996 Quote Link to comment

My single 128GB SSD is indeed BTRFS. I will add/format the 500gb and then add those commands you outlined. Thanks for being so knowledgeable about BTRFS! And double thanks for sharing that!!

Scintilla13 Posted March 18, 2020 Share Posted March 18, 2020 I have the same question, but in this post there is no link to a solution neither which configuration implement. Please could you help me on how to configure a BTRFS JBOD cache volume with replaceable devices? Quote Link to comment
