[TECH] SMART, SMARTCTL AND THE LONG CHECK

2006 July 23 | 0 comments

As meantioned earlier, I have my three 250 GB IDE harddrives set up like this:

md5 : active raid5 hdb8[0] hdc8[2] hda8[1]
451426304 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]

md4 : active raid5 hdb7[0] hdc7[2] hda7[1]
13992320 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]

md3 : active raid5 hda6[0] hdb6[2] hdc6[1]
8000128 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]

md2 : active raid5 hdb5[0] hdc5[2] hda5[1]
5991936 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]

md1 : active raid5 hdb3[0] hdc3[2] hda3[1]
5992064 blocks level 5, 64k chunk, algorithm 2 [3/3] [UUU]

md0 : active raid1 hdb1[0] hdc1[2] hda1[1]
497856 blocks [3/3] [UUU]

To get regular information about the health of my discs, I use hdtest once a day. hdtest runs a S.M.A.R.T. short test on Monday through Saturday night, and a S.M.A.R.T. long test on Sunday night (well, 3 AM really).
What I didn't think of back then, at 5 AM /etc/cron.daily/ is executed which contains - among others - a run of updatedb. Well, it is now *checks the clock* 09:48 AM and updatedb is still running, the S.M.A.R.T. tests are at 80% done (hda and hdb) and 50% done (hdc) and the load is around 6 (on a dual 800 MHz machine).

I must admit I've had more fun already :(
