Do the tests require a particular minimum size? see more about the hardware here https://wiki.sepia.ceph.com/doku.php?id=hardware:smithi cmeno@smithi110:~$ sudo pvs PV VG Fmt Attr PSize PFree /dev/nvme0n1 vg_nvme lvm2 a-- <372.61g 100.00m cmeno@smithi110:~$ sudo lvs LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert lv_1 vg_nvme -wi-a----- 89.40g lv_2 vg_nvme -wi-ao---- 89.40g lv_3 vg_nvme -wi-ao---- 89.40g lv_4 vg_nvme -wi-ao---- 89.40g lv_5 vg_nvme -wi-ao---- 14.90g cmeno@smithi110:~$ cheers, Christina > > > I've been telling the aarch64 folks that we probably want at least 25-50 > > similarly-sized nodes in order to run the test suites in a reasonable > > amount of time (e.g., minimal rados suite ~day and not days). > > > > I'm not really sure how this maps on the Z hardware, but hopefully this > > provides some guidance! > > Yes, it does! We'll certainly have to tune this is a bit depending on how everything performs on Z hardware, but this gives us a starting point. > > Bye, > Ulrich > _______________________________________________ > Dev mailing list -- dev@xxxxxxx > To unsubscribe send an email to dev-leave@xxxxxxx > > _______________________________________________ Dev mailing list -- dev@xxxxxxx To unsubscribe send an email to dev-leave@xxxxxxx
