General Operating Guidelines and Limitations
StorNext User’s Guide 341
All UNIX and Linux In a file system configuration file, if the Metadata parameter for a stripe group
was set to
Yes when the file system was created, do not later change the
parameter to
No. Doing so will cause the metadata to become inaccessible and
result in errors. Also, if the parameter is changed to
No, the cvupdatefs
command might allow bandwidth expansion of the stripe group, resulting in
metadata corruption.
Solaris On Solaris, by default, the
/usr/lib/fs/nfs/nfsfind script is run nightly by the
cron daemon. This script contains a find command that traverses any local file
system that is exported (shared) via NFS. If the running of this script is
interfering with the performance of processes accessing StorNext file
systems, it can be modified to skip them. To do so, add the following line to
the
find command in the script:
'(' -type d -fstype cvfs -prune ')' -o
The final find command should look like this:
find $dir '(' -type d -fstype cvfs -prune ')' -o -type f -name .nfs\* -mtime +7 -mount -exec
rm -f {} \;
The Solaris Security Toolkit, formally known as JASS, causes the following
two issues:
• It disables RPC by renaming the RPC startup script, disrupting the
StorNext interprocess communication. To fix the communication problem,
rename the RPC startup script in
/etc/init.d from rpc.<illegal extension> to rpc.
• It turns on IPSec, causing numerous warning messages in the system log
file. Either disable IPSec by removing the IPSec startup file in
/etc/init.d or
contact Sun Technical Support to find out how to reconfigure IPSec to
ignore local loopback connections.
Windows Windows Services for UNIX (SFU) supports only NTFS for NFS exports.
Because of this limitation, a Windows system cannot act as an NFS server for
StorNext File System.
When a StorNext file system is mounted to a drive letter or a directory,
configure the Windows backup utility to NOT include the StorNext file
system.
