General Operating Guidelines and Limitations

Description

 

 

All

The Move Stripe Group Data feature (part of Dynamic Resource Allocation)

 

does not support moving sparse files. Sparse files are files that lack on-disk

 

allocations for some of the data within the data range indicated by the size of

 

the file.

 

A stripe group is defragmented as part of the data moving process. Because

 

defragmenting a sparse file would make it unsparce (and increase disk

 

usage), snfsdefrag skips sparse files when defragmenting. Therefore, all

 

existing sparse files remain on the original stripe group after moving of other

 

files is complete.

 

As an example, the gnu “cp” command uses a heuristic to attempt

 

maintaining the “sparseness” of a file.

 

Because the file system in question has already had the source stripe group

 

marked read-only, the “cp” command has no choice but to move the file off

 

of the original stripe group.

 

 

 

Clients outside a NAT firewall can no longer access a metadata controller

 

inside the firewall.

 

Support for client access through non-NAT firewalls continues to be

 

supported via the fsports configuration file.

 

 

 

If you have configured custom mount options in the /etc/fstab file other than

 

rw and diskproxy, if you subsequently add or remove the disk proxy settings

 

using the StorNext GUI, any custom mount options will be lost. (Settings are

 

added or removed in the StorNext GUI by navigating to the SNFS home page

 

and then choosing Filesystems > Modify from the Config menu.)

 

 

 

In StorNext 3.0, the buffercachemin and buffercachemax parameters are

 

deprecated and are replaced by buffercachecap.

 

Also, in the Client Configuration Windows utility, the Buffer Cache Min and

 

Buffer Cache Max settings are replaced by Buffer Cache Cap. The Non-Paged

 

Pool Percentage setting has been removed.

 

 

 

If you use an SDisk or DDisk, you should save at least one other copy of the

 

data to tape or to another SDisk or Ddisk. Without the second copy, your

 

stored data will be vulnerable to data loss if you ever have hardware failure.
