Eponymous

Excluding directories while using pax(1)
My primary disk is failing. There are large segments that are generating low level IO errors during read or write operations. Most of the files written to the bad area were under /usr/ports/ where the FreeBSD Ports collection is installed. A few files were under the web server's root.

Figuring I'd take care of things prior to the disk actually failing to the point of it being irrecoverable, I purchased a new disk early. I installed it, partitioned it, and formatted it.

To copy the data over, ignoring the areas that were causing the IO errors, I used mv to "move" the files from the web root under /usr/ports and used the following command as root:

pax -rwvpe -s':/usr/ports/.*::gp' -X / /mnt/newdisk/

The -X prevents pax from traversing into mount points that have a different device ID than the one on which it was started. This prevents an infinitely recursive loop from happening when the new disk's mount point would have been hit. It also prevents data on the non-failing disks from being copied as well.
the -s option allows for sed search and replace scripts to be run. In this example, the : is used as the delimiter and any path matching /usr/ports/* is replaced by a null string. With this replacement all directories under /usr/ports are excluded from the copy.

Sleep.	03 Jun 2008 Demo In the next few weeks we are going to attempt to record and roughly mix a demo of a short track which will serve as an introduction to the album. Currently known as 11, it is a very short piece in 4/4 time at 80bpm. It is in the key of B minor and the spoken words are taken from a quote attributed to Nietzsche. What upsets me is not that you lied to me, but that from now on I can no longer believe you. This short demo will hopefully get me motivated enough to put more time into the album. More information will be posted when it becomes available. [/album] [permanent link]
