Randall Eggert Sand Springs, Oklahoma [email protected] 2/7/2016 gtar abends apparently stuck in a loop while backing up the primary device on my Mac. Iâm backing to an external drive attached via FireWire-800. The included text below shows it start looping on /devâ¦. Massive amount of this text appears while finishing/aborting the backup, which is identically repeated when listing the backup. Duplicate backups done several days previously did not do this. I had several external disks mounted before I started the backup that I dismounted to turn off the drives before starting. scripts/dismount.sh #!/bin/sh for i in `df -lh | cut -f1 -d' '| grep /dev | sort -r ` do diskutil unmount $i done Perhaps not the best way to dismount volumes, those active receive an error that they are in use, but everything else gets shut down. (keeps the noise down) ran Verify on both source and target drives (Journaled HFS Plus volumes) with Disk Utility and both were clean Mac mini - Early 2009 OS X 10.9.5 (13F1603) 2 GHz Intel Core 2 Duo 8 GB 1067 MHz DDR3 Mac250SSD 07:13:29 7 Desktop $gtar --version tar (GNU tar) 1.28 Copyright (C) 2014 Free Software Foundation, Inc.
