Hi
I am running the install_vertica script and it doesn't get past the checking. I am receiving the following errors/warnings. Note that I've already adjusted the scheduler for sda to deadline. I checked the mapping of these lv partitions and I see they are dm-0 and dm-2. The only scheduler mentioned is "none" in those files. Here is the message:
Prerequisites not fully met during local (OS) configuration for
verify-xx.xx.xx.xx.xml:
HINT (S0151): https://my.vertica.com/docs/7.2.x/HTML/ ... shid=S0151
These disks do not have known IO schedulers:
'/dev/mapper/vg_myserver1-lv_home' ('') = '',
'/dev/mapper/vg_myserver1-lv_root' ('') = ''
WARN (S0170): https://my.vertica.com/docs/7.2.x/HTML/ ... shid=S0170
lvscan (LVM utility) indicates some active volumes.
I guess I am missing something here. I was trying to search the Linux forums too. I know that lvm is not supported but this is how the server was before. I just reinstalling the OS and vertica again for a new setup.
Thanks for any help.

Check out:
Make sure to set the scheduler parameter in the config file so that the change is permanent.
If you are working in a DEV system, you can use the --failure-threshold NONE install option to ignore all warnings and failures...
