Was doing some work on Saturday w/ my main ZFS pool I have my wife's most precious data on (fam photo's/vids/photography business/client data/etc.) removing ZIL device, removal of the hussl went off w/out a hitch manually from cli, I went to add the ZeusRAM as ZIL and did not see it in menu's initially, thought to myself 'screw this I know how to add manually'...added manually but noticed it didn't add by GPT UUID so that pissed me off. Removed and sg_formatted, tried to add back in via GUI, this time I saw the add as log device to pool button...executed....WAIT FOR IT...somehow effing added as a stripe vdev and NOT a log device w/in pool but not in raidz2 vdev...wtf, must have missed a button I thought I pressed. Fark, 6TB resilver at a MAD rate, think ZeusRAM was gettin' hit hard. Found out I effed myself and had to blow away pool to cleanup my boo boo.
Here's where the story comes full circle/main takeaway
I replicate that buggered up pool daily to my other ZFS box w/ a raidz pool of six 4tb seagate expansion shuckers and 2 hussl slc ssd's as L2ARC/ZIL via scheduled snapshots and replication tasks. I had the day before point in time at 12:10pm for sure and two weeks older than that if needed! WHEW!!! Backed up whatever other outlier data I needed to via zfs snapshot send/recv's between FreeNAS boxes, blew away pool and zfs send/recv back to fixed pool w/ ZeusRAM setup as ZIL properly at about 300-400MB/sec :-D Took about 4-6 hours to restore 6TB of data roughly.
Who was the hero of the day...ME so says my wife, good data protection strategies/methodologies in practice! Wooohooo
She even came downstairs and gave my servers a lil' pat on the head/chassis lid :-D
Anyone else smell that???JUSTIFIED SERVER/STG BUDGET!!! BWA HAHA
Filling up my shopping cart now!
