The solution is to adjust a few parameters on the Cache Parameters tab in the SNFX control panel (cvntclnt). These parameters control how much memory is consumed by the directory cache, the buffer cache, and the local file cache. As always, an understanding of the customer's workload aid in determining the correct values. Tuning is not an exact science, and requires some trial-and-error to come up with values that work best in the customer's environment. The settings in the Cache Paramete

Configuring LDAP The following information describes how to configure the new StorNext LDAP feature in addition to outlining recent changes to Windows configuration tools. Using LDAP SNFX 1.3 introduces support for Light Directory Access Protocol, or LDAP (RFC 2307). This feature allows customers to use Active Directory/LDAP for mapping Windows User ID's (SIDs) to UNIX User ID/Group ID's. Changes to "Nobody" mapping As with previous releases, if a Windows user cannot be mapped to a Unix ID, t

Navigating to the Windows File System Control Parameters pane > Authentication tab gives the administrator the ability to disable the NIS/PCNFSD mapping on a client by client basis by checking LDAP. Domain Server Requirements The domain server must be at least Windows 2000 or above to support RFC 2307 mapping. Client Requirements Mapping is done by searching the domain server that the Windows machine is a member of. The user must be logged in under the user account owned by that domain server.

Limitations This table lists the limitations that have been discovered in this release of SNFX. Operating System/ Description Component Affected 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 so

Operating System/ Description Component Affected 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 cvf

Operating System/ Description Component Affected 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
