While in the past it performed many functions, the archiver's remaining take is to move Raw data + FastCopy data to tape via "astore". Due to losing the ability to obtain an AFS token, much of the archiver's functionality has been lost, including the ability to clean up data on wain031 that has already been backed up. Steve now does this manually. The erase occurs when both files "astoredone" and "xrootdone" are created, meaning that both backups have been performed and the age of the raw data is sufficient.
on wain031: Note that there is a replacement disk, and there is a slow copy of this area occurring now.

Steve's opinion is that we should replace the archiver rather than attempt to fix it up.

"astore" is deprecated, Computing Center is planning to discontinue its use at some undetermined time in the future. Brian suggests we may have 2 years, but that needs to be confirmed by the Computing Center. Andrew May is the current "astore" maintainer. Richard also mentions that Lance is very helpful.
- Deal with old data
- Provide alternate "astore" capability for future data.
The idea was floated to migrate all the old data, but that would likely require hundreds of hours of I/O.
Richard confirms that we have plenty of tape available.
Steve owns the L0 task.
Rob asks about the DTR task contained in the fastCopy archive. Steve indicates that no changes are required for the DTR task if astore is replaced. "astore" only handles back ups.
CHS package
handles unpacked LAT raw data, lsf an ldd formats. This is used heavily by the half-pipe which extracts evt files and passes them to L1
