tce/opt/home/etc on remote shares
« on: January 26, 2020, 09:05:39 AM »
Good day, all!

I've been ripping apart tc-config and tce-setup trying to trace out the paths/functions used for different mount options regarding persistence and pieces look to be missing (or I'm simply not seeing them!)
For example, tce=aoe I'm not seeing supported in either file (nor have I yet tested mounting a remote disk via AoE and then point tce/opt/etc. to it.  Please point me in the right direction if you would - IF it's supported and I just didn't see where.)
I'm creating another boot code / mount option which is going to be treated in the same fashion as tce=nfs opt=nfs but I want to make sure there aren't other areas or files I have to dig into first (thus my finding the missing AoE support for tce=aoe opt=aoe, etc.)

Hi centralware
As I recall, gerald_clark worked on implementing Aoe. You might find some more details if you go to:
Then set the  Search for:  field to  aoe  and set the  By user:  field to  gerald_clark.

Hello, Rich!

Yes, Gerald was the one who introduced AoE onto TC, but the question here is more focused on tc-config/tce-setup as to where and how things like AoE, NFS, NBD, etc. are located in regards to setting up tcedir and persistent directories.

NFS, for example, is mounted via /etc/init.d/tc-config and when tce-setup is launched, the mount (and command-line) are detected and the NFS mount then takes over as the TARGET of where tce, opt, home and/or local are to be set up from.  (AoE I just mention as I don't see any mention of it being usable AS tce/opt/etc. in source.)  If none of the above are found or requested, it falls back to /tmp/tce in tce-setup thus making the entire session temporary.

My question is/was...  are there any other files relating to setting up tce/opt/home/local/etc. that get launched at boot time (one of which might even have the missing AoE persistence support?)

...to be more specific, are there any other files that are boot related, pertaining to etc/sysconfig/tcedir, opt and home directory persistence which are not the following:

etc/init.d/tc-config          Handles mounting items listed in the command-line
etc/init.d/tc-functions      Support file; find_mountpoint and autoscan functions
usr/bin/tce-setup            Used to mount etc/sysconfig/tcedir and prep directory/files
