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

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

  • /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)
