[Twg] Requirements

[Atul Vidwansa]

Here are some requirements I captured during my discussion with customers:

1. Replication on network: Ability to replicate data as per user policies. User should be able to specify how many copied of certain data he wants. Simplest form is to do RAID1 like mirroring along with data striping.

2. Ease of management: A central console like utility that can show status of clients and servers, performance data, availability, ability to drill down from logical to physical components to check health, plugins for integrating with Nagios/Ganglia. Letter versions of such tool cold provice features like storage and user accounting, ability to track filesystem uptime.

3. Streamlined patching mechanism: Lustre currently has ad-hoc patching mechanism with no scope of dependency checking. A mechanism to fetch patches from central repository, check dependency, ability to apply and rollback,  easy upgrades, ability to display currently applied patches  etc

4. Built in failover: No dependency on external packages like heartbeat/pacemaker, ability to have more than 2 nodes in failover group, quick failover of node, network or services.

5. Better diagnostic messages: Log messages that tell system administrator what is wrong and further course of action. No cryptic messages. 

6. Better use of flash devices: Either as intermediate cache or for increasing disk rebuild times.

Cheers,
_Atul

Unfortunately, I haven't gotten any replies to the emails that I sent out.
