IO scheduler during vertica 7 install failure
During the install, we get:
These disks do not have known IO schedulers: '/dev/mapper/rootvg-varlv'
('') = '', '/dev/mapper/rootvg-usrlv' ('') = '', '/dev/mapper/rootvg-
tmplv' ('') = '', '/dev/mapper/rootvg-optlv' ('') = '', '/dev/mapper
/rootvg-homelv' ('') = ''
So we execute:
cat /sys/block/sdb/queue/scheduler
noop anticipatory [deadline] cfq
We also tried:
cat /sys/block/sdb2/queue/scheduler
noop anticipatory [deadline] cfq
Because from our /etc/fstab, this is our partition:
/dev/sdb2 /u01 ext4 defaults 1 2
I believe this one won;t allow the install to continue.
What can be done to get beyond this problem?
These are the other issue:

TZ is unset for dradmin. Consider updating .profile or .bashrc

How critical are these?

By default Linux scheduler is set to cfq ("completely fair queuing"). Vertica recommends using deadline or noop.
To see how your system is set;
# cat /sys/block/sda/queue/scheduler
noop deadline [cfq]
The setting is the one enclosed in brackets []
Please send me the full error message on installation failing.
Regarding you second part of the questions, There is link to document is provided against each message. Request you to please got to that link for more information.
