IRIX

SNFS uses 64-bit inode numbers. 32-bit applications (programs compiled

 

without 64-bit) support may experience problems working with files with

 

inode numbers greater than 2147483648. 32-bit applications may also

 

encounter problems when dealing with files greater than 2TB in size, This

 

issue is not unique to StorNext, but may be encountered by some legacy

 

applications when working with SNFS on IRIX.

 

 

 

StorNext only supports SGI 64-bit versions of IRIX on operating systems

 

that use the SGI version of the QLogic QLA2200 or QLA2310 FC-HBAs.

 

 

 

Use the uname -aRcommand to determine the running version of IRIX.

 

• If you are using IRIX level 6.5.26, you must install the maintenance

 

 

stream of StorNext or SNFS.

 

 

 

On many versions of IRIX, the root crontab contains the following entry

 

which is used to remove old application crash dumps and temporary mail

 

files:

 

find / -local -type f '(' -name core -o -name dead.letter ')'

 

-atime +7 -mtime +7 -exec rm -f '{}' ';'

 

If StorNext file systems are mounted, they will be traversed by this find

 

command which can have a dramatic impact on the performance of other

 

applications currently using these file systems. To prevent the traversal of

 

StorNext file systems, modify the find command so it reads:

 

find / -local '(' -type d -fstype cvfs -prune ')' -o -type f

 

'(' -name core -o -name dead.letter ')' -atime +7 -mtime +7 -

 

exec rm -f '{}' ';'

 

 

Linux

On many versions of Linux, the cron system runs a nightly script called

 

slocate.cron that is used to build a database used by the slocate

 

command. If StorNext file systems are mounted, they will be traversed by

 

this cron job which can have a dramatic impact on the performance of other

 

applications currently using these file systems. To prevent cron from

 

traversing StorNext file systems, two files need to be updated. Perform

 

these steps:

 

1

Modify the updatedb command in the /etc/cron.daily/slocate.cron file to

 

 

read:

 

 

/usr/bin/updatedb -f

 

 

"cvfs,nfs,smbfs,ncpfs,proc,devpts" -e

 

 

"/tmp,/var/tmp,/usr/tmp,/afs,/net"

 

 

NOTE: "cvfs" has been added to the exclude list.

 

2

Add cvfs to the PRUNEFS definition in the /etc/updatedb.conf file.

 

 

For example:

 

 

PRUNEFS="cvfs devpts NFS nfs afs proc smbfs autofs

 

 

auto iso9660"
