We have lots of 2.5'' SAS drives from a decomissioned EMC AX4 array (Seagate Savvio 10k.3), and would like to install on HP Proliant 360pG7. Proliant does not detect those drives, is there something we are missing or is this hopeless?

Let me clarify: we don't want an HP supported solution, we would like to know if it is possible for the disks to work. These servers are for dev/testing.

/dev/sdb has LVM and exposes a single logical volume, dm-0.

While writing to dm-0, /proc/diskstats reports:

# of writes completed
sdb 29646717
dm-0 131315099

# of writes merged:
sdb 101668283
dm-0 0

That means that /dev/sdb statistics report that most of the writes have been merged, so it report much lower total writes, while the lvm device does not. Which counters are more indicative of the actual write IOPS detected by the lower layer (e.g. AWS provisioned IOPS?)

we need to delegate management of several instances through AWS console to one of our clients. For this purpose we created a new IAM group.

We need this group to only list and modify specific EC2 instances, e.g. using a tag. We tried using the read-only ec2 template, and modifying it by adding:

  "Statement": [
    {
      "Effect": "Allow",
      "Action": "ec2:Describe*",
      "Resource": "*",
      "Condition": {
         "StringEquals": {
            "ec2:ResourceTag/Tenant": "clientname"
         }
      }      
    },...

This unfortunately results to "You are not authorized to describe Running Instances" for the aws console, and no instances are shown, although the correct tag exists. Please advise on how can we filter instance listing based on tags or other methods (e.g. VPC id).

I want only user "theuser" to login to this host.

I have tried the following in nslcd.conf:

pam_authz_search (&(objectClass=posixAccount)(IsActive=TRUE)(uid=theuser))

but all can login. If instead of pam_authz_search I use the "filter" command, it works, but getent returns only one user, the "theuser".

UPDATE: OS is ubuntu 12.10, I'm using libpam-ldapd NOT libpam-ldap
