DB server installation

  • the osdserver process is installed with the dedicated openafs-osdserver RPM

  • for this RPM, there is a dedicated repository in SL/53/x86_64_extra/afs-osdserver

  • in vamos, this repository is selected by the CF_YUM_extrarepos_afsosddb variable

    • it was included in the afs-dbserver-mod

Enabling clients for OSD + Vicep-Access

  • handled by the afsosd-mod

    • install proper AFS client + module (afs1410osd-alma repository)

    • install SLZ_vicep_lustre_links RPM /!\ not in modifier yet

Original setup for a Lustre-based vice partition

  • once Lustre is available, setup the partition

    • create the appropriate link to lustre (must match the link distributed to clients via RPM) 

      [zyklop20] ~ # ln -s /lustre/vpxl /vicepal

    • do create the AlwaysAttach file (otherwise, non-partition /vicep directories are ignored) 

      [zyklop20] ~ # touch /vicepal/AlwaysAttach

    • protect the "vice partition" from fileserver usage: 

      [zyklop20] ~ # touch /vicepal/OnlyRxosd

  • launch the rxosd process 

    [zyklop20] ~ # bos create localhost rxosd simple /usr/afs/bin/rxosd -localauth
    • this has no immediate effect, vice partitions are touched once the osddb asks for them
  • add the appropriate OSDDB entry

    • <!> you have to use an id and name never used before

    • /vicepal => lun = 1 * 26 + 11 (where a corresponds to 1 and l to 11 (=12-1)) 

      osd createosd -id 2 -name zyklop20-al -ip 141.34.22.43 -lun 37 -minsize 1m -maxsize 2048g -wrprio 64 -rdprio 64

    • /!\ this requires AFS admin privileges, of course (currently, osd createosd has no -localauth)

Setup for an archive vice partition

  •   # bos create localhost rxosd simple /usr/afs/bin/rxosd -localauth; bos start localhost rxosd 
  •   # touch /vicepa/AlwaysAttach /vicepa/OnlyRxosd
  •   # osd createosd -id 4 -name arch -ip 141.34.32.37 -lun 0 -minsize 0kb -maxsize 10g -wrprio 64 -rdprio 64 -archival 
  •   # bos restart localhost rxosd
