Custom Query – smartmontools

Description

I love the selective self tests feature (-t select,min-max/next/cont[+SIZE]). The long tests just take too long. However I can't get it to work right with smartd.

My configuration is this:

smartmontools version 6.2

smartd started with --savestates=/var/lib/smartd/ and verified that state files actually appear in that location

smartd.conf with -a -s c/../.././17 for all disks

My issues are these:

when I -t select,min-max a disk (to get things started), this info usually does not make it into the state files. And without the state files nothing works as my WDC disks don't seem to keep the data across reboots

after adding selective-test-last-start/end manually to the state files, things *seem* to work for a while. But it seems to forget the range size after a couple of days, probably when it reaches the end of the disk?

one of the disks is a SSD (Crucial M4 64G), and I did a -t select,0-max on it in an attempt to make the cont check always check the entire thing. What happens instead is that smartd actually checks nothing (0-0) every time and the last start/end vanishes from the state file. (I'm aware I should just make an extra config entry for the SSDs that use long tests as they don't take long on SSDs.)

If possible I'd like to be able to specify the SIZE directly in smartd.conf the same way it's possible to do on the command line (-t select,cont+SIZE). Ideally this should also remove the need of running the first select test manually.

It would be cool if SIZE could be specified as a percentage, so for example a DEFAULT entry that checks 5% of a disk could be made regardless of disk sizes.

Description

Right now smartmontool could not gather metrics from devices without root access, because to open device with O_RDONLY mode. It is explained in source code as a way to avoid spindle spin-up when device is closed. Unfortunately this made impossible to use all SG_IO commands, as they require RDWR access to the device.

My proposal is to add device types 'scsi-rw', 'sat-rw', 'ata-rw', etc to allow to run smartmontools with limited capabilities and permissions (e.g. not from the root).

Description

These are some China (PRC) based cheap SSDs being sold in India. By a company called Nextron under model / brand name called NForce.

Surprisingly, in spite of being cheap they have 5 year warranty.

Here is output of: smartctl -x /dev/sda
