[NTLUG:Discuss] compression and Filesystem question

[Richard Geoffrion]

As it pertains to using cheap IDE drives in SCSI converter trays for offsite
storage and nearline archival storage....

1.) Is there a file compression file-type that can be mounted as a
filesystem?  Can one mount a tarred.gz?  What about a compressed ISO?  I
guess read only would work.

2) Are there any file compression programs that will ABORT and just STORE a
file if the file compression utility can not compress the file by $X%?
Didn't/doesn't ZIP compression do something like that?

3)  Has anyone ever hot swapped a software raid set? Can it be done?  How
does Linux handle the hot swapping of multiple 'three drive hardware RAID-5
disk sets'?
