Starting from Update 7 pstorage top command allows to view the disk info provided by smartctl tool installed along with Virtuozzo storage.

However, after pressing 'd' to switch to the disks table, not all disks in cluster are listed


pstorage top command relies on smartctl output which is different for SATA and SCSI disks or disks attached to a raid controller. pstorage top supports disk monitoring only for SATA disks.

For example, the following smartctl output cannot be parsed by pstorage monitoring script:

# smartctl -A -i /dev/sdb 
smartctl 5.43 2012-06-30 r3573 [x86_64-linux-2.6.32-042stab102.9] (local build)
Copyright (C) 2002-12 by Bruce Allen,
Smartctl open device: /dev/sdb failed: DELL or MegaRaid controller, please try adding '-d megaraid,N'

As result, corresponding disk will be omitted in pstorage top

This behavior recognized as product issue #PSBM-31421


S.M.A.R.T disk monitoring support for other disk types will be implemented in one of the future Virtuozzo Storage Updates.
