All

With SNFX 1.3, a change has been made to the way that the Reserved

 

Extents performance feature affects free space reporting. In the previous

 

release, SNFS would reserve a certain amount of disk space which would

 

cause applications to receive an out of space error before the disk

 

capacity reached 100%.

 

 

 

 

In the current release, this reserved space is treated as allocated space.

 

This allows applications to perform allocations until the file system is nearly

 

full.

 

 

 

 

NOTE: Due to allocation rounding, applications may still

 

 

receive a premature out of space error, but

 

 

only when there are only a few megabytes of

 

 

space remaining. In the worst case, the error

 

 

will be returned when the reported remaining

 

 

space is:

 

 

 

 

(InodeExpandMax * #-of-data-stripe-

 

 

groups)

 

 

 

 

One side effect of this change is that after creating a new file system, df

 

will show that space has been used, even though no user data has been

 

allocated. This amount of reserved space is determined by the following

 

formula:

 

 

 

 

reserved space megabytes = (MaxConnections - 1) *

 

 

MaxMBPerClientReserve * #-of-data-stripe-groups

 

 

For example:

 

 

 

 

1 TB file system, 4 data stripe groups, MaxConnections=25,

 

MaxMBPerClientReserve=100

 

 

 

After cvmkfs has been used to create the file system, df reports:

 

File system 1K-blocks

/snfs1

While not recommended, the Reserved Extents feature can be disabled by applying the following setting to the Globals section of the FSM configuration file:

MaxMBPerClientReserve 0

This will cause the file system to not reserve space, but will reduce I/O performance in some cases.
