IRIX | SNFS uses | |
| without | |
| inode numbers greater than 2147483648. | |
| 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 | |
| that use the SGI version of the QLogic QLA2200 or QLA2310 | |
|
| |
| Use the uname | |
| • 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 / | |
| ||
| 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 / | |
| '(' | |
| exec rm | |
|
| |
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 |
|
| "cvfs,nfs,smbfs,ncpfs,proc,devpts" |
|
| "/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" |
