With 10 minute samples anything that happened gets averaged enough that even the worst event is almost impossible to see. Sar will report the same as date ie local time. And a 12:51 event would be in the 13:00 sample (started at about 12:50 and ended at 1300). What I do see is that during that w

Since it is home, I would edit fstab and change "defaults" to "defaults,nofail" that will result in the system booting up if/when home is missing. Then you can look at what is going on with home with the system booted and all tools. Rule #1: avoid emergency mode and get the system on the network
