-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 In the past week or so some in my computer procedures have become sluggish, and some others have not worked at all.
For example the following script works: #! /bin/bash CURPWD=$PWD cd /home/ken tar -czf /media/fde/backups/kfinancescurrent.tgz --wildcards\ - --exclude-from=docs/tarlists/kfinancesarchive.lst docs/01-kens/Finances cd $CURPWD Whereas this one does not work now but did two weeks ago: #!/bin/bash # Shell script to create a tgz file for the contents of the # /home/ken/docs and the /usr/local/ directories, # minus the files in file /home/ken/docs/tarlists/kexcludedocs.lst # This script may be run from any directory to which the user has write # permission. # Start by creating a variable with the current directory. CURPWD=$PWD # Change directory to / cd / # Create the tarball. tar -czpf media/fde/backups/kdocsfull.tgz -X /home/ken/docs/tarlists/kdocsfullexclude.lst -T /home/ken/docs/tarlists/kdocsfullinclude.lst # Return to the starting directory. cd $CURPWD Now when I try to run it it returns the following: ken@SOL:~$ tar -czpf media/fde/backups/kdocsfull.tgz -X /home/ken/docs/tarlists/kdocsfullexclude.lst -T /home/ken/docs/tarlists/kdocsfullinclude.lst tar (child): media/fde/backups/kdocsfull.tgz: Cannot open: No such file or directorytar: home/ken/docs: Cannot stat: No such file or directory tar: usr/local: Cannot stat: No such file or directory tar (child): Error is not recoverable: exiting now tar: Child returned status 2 tar: Error is not recoverable: exiting now All the files/directories which this script cannot stat do in fact exist, proven by the fact that the first script uses the same directories, but different files in those directories. As these symptoms can indicate I think hard drive failure or potential failure I am trying to explore this possibility. I am using Stretch and TDE with two 2 TB Seagate Barracuda hard drives in a RAID 1 configuration. Both drives were purchased at the same time and were installed in the box on 2016-05-30. Although hree and one half years ago, this particular box is only used six months out of twelve. I would not have thought that drives -- if they last the first year -- would not show signs of failure after 1.75 years. In any event, I ran smartctl -a on both drives. For both "SMART overall-health self-assessment test result [was] 'PASSED'" Nevertheless for all the specific attributes, identical for both drives, three of them had the indication 'Pre-fail' and 'Old-age' for the other nineteen. I also ran 'badblock -v'. Both had 1953514583 blocks. The test for /dev/sda was interrupted at block 738381440, and for /dev/sdb at block 42064448. I am not sure what all these test results mean, or how accurate they would be for indicating if or when a failure would occur. It did occur to me that if after copying all my data files to an external hard drive I could replace the /dev/sdb device with a new one and copy all the data in /dev/sda on the assumption with a new and presumably pristine drive the OS given the choice would access the data it wanted from the drive which responded the quicker. If that approach worked I could replace the other drive in another year or two (really one year of use) so that both drives in the RAID 1 would not be of the same age. Comments and advice as to the best way of getting this computer back to 'normal' to the extent that such a state could ever be 'normal'.
