Hi Adam
I think it should be easy by changing the macro variables, I think we did this before and it was working, just make sure that you have read/write permissions on the new locations otherwise all your PVs will remain in the “Appliance Assigned”
state. For your 2nd question, STORAGE_TOP is optional, the three storage locations definitions are independent, it is not mandatory for the locations or mount points to share the same “STORAGE_TOP”, you can specify each store in the appropriate
mount point in your setup.
If you have enough RAM on your server, it is best practice to setup the STS using a RAM disk (the tempfs filesystem), this will improve performance on data retrieval for recent periods.

Hey All,
I am planning on changing where our STS MTS and LTS are stored. Most likely will use STS MTS on the local SSD I have but wanted to move our LTS over to a NAS or some external storage. Wanted to know if there are any pitfalls to setting
this up or is at as easy as changing up these values in the archappl.conf? Also was wondering about what STORAGE_TOP does if say my LONG_TERM_FOLDER does not share the same STORAGE_TOP directory for example?
ARCHAPPL_STORAGE_TOP="/arch"
ARCHAPPL_SHORT_TERM_FOLDER="/arch/sts/ArchiverStore"
ARCHAPPL_MEDIUM_TERM_FOLDER="/arch/mts/ArchiverStore"
ARCHAPPL_LONG_TERM_FOLDER="/Network/lts/StorageExample "
Thanks,
Adam
