I have found nothing up to now. If you consider the commercial cost
of an HSM, they aim their market towards high-end servers. I do
not know if they ever heard about Linux.
However, tape libraries are not so expensive now, and Linux servers are
powerful and reliable(300 GB harware RAID on line on my linux NFS
servers 2.2.x. Will double next year).
Would not it be a good challenge for a developper to modify an ext2fs
into an HSM by :
- adding tape information (on-line|near-line|off-line flag, tape bar-code,
file index on the tape) to the i-node sructure,
- writing the code to restore near-line/off-line files and to swap old files,
- modifying file access utilities and services (ls, ftp, nfs ??)
Unfortunately I am not a developper. Just a user.
