Hello everyone,

My freenas server has been slow lately, and I have been getting tgheodd GUI update with errors/pending issues with the HDD at ada1. I ran a long SMART test last night - can anyone help me interpret these results (never really read a SMART report before...)

  After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.

Code:
  5 Reallocated_Sector_Ct   0x0033   097   097   010    Pre-fail  Always       - 3848 
197 Current_Pending_Sector  0x0012   046   035   000    Old_age   Always       - 8904


There are 3848 bad blocks on the drive, and also 8904 undecided, which are supposedly defective, but that's to be decided at some later time (in fact, these are also defective). The drive is to be replaced under warranty, or discarded if it is not possible.

I see a long list of short SMART tests in the drive data, but only one long SMART test. I don't know what your testing frequency is normally but there appears to be about 2000 hours between the last short test and the failed long test. I would suggest setting your system up to do daily short tests and weekly long tests on the drives and take the test results seriously.

The number of hours on this drive is around 4 years so it is probably well beyond the warranty period and I would suggest you start planning to replace all the similar drives you are using. I use Seagate Barracuda drives also and the last batch I had started to fail regularly between the four year and five year mark. I was replacing a drive every month up to when I had two failures on the same day. Then I bought a bunch of new drives and replaced them all.
They are just getting close to the end of life. Time to plan for it.
