[gpfsug-discuss] Max number of vdisks in a recovery group - is it 64?

[Dietrich, Stefan]

Hello Heiner,

the 64 vdisk limit per RG is still present in the latest ESS docs:
https://www.ibm.com/support/knowledgecenter/SSYSP8_5.3.5/com.ibm.spectrum.scale.raid.v5r04.adm.doc/bl1adv_vdisks.htm

For the other questions, no idea.

Regards,
Stefan
