How to increase max filesize limit in HPUX filesystem?
Hello Experts,
One of our customer is having a requirement to increase the maximum filesize limit to 2GB of a particular filesystem in HPUX? (without downtime & without losing data). His query is as follows:
"Can you please make all the /db02 filesystem as big file system?
Currently it doesn't allow growing a single file larger than 2G "
Please let me know wheather it is possible in HPUX. If Yes, please let me know the steps.
I have shown you some results about that filesystem in the snippet.
Thanks,
Ashok

Thanks for your solution. In addition, i would like to share one feature in HPUX, which allows to do filesystem operations online (One of my friend has suggested me this solution). Its OnLineJFS. If we have a licensed version installed on the machine, we do filesystem operations like extending, increasing filesize limit, without unmounting the filesystem. To check whether OnlineJFS is enabled or not, we can use the following command:
/sbin/fs/vxfs3.3/vxenablef
vxenablef displays the licensed features enabled in the kernel. If
OnLineJFS features are enabled, it will print the following:
System is licensed for features
Full_VxFS HP_DMAPI <-- It should display like this.
Thanks again for your inputs.

Thank you very much for the additional feedback!
