In short: I´m building computer systems with mounted iSCSI storage. Is it possible to extend the iSCSI storage in live operating without rebooting the systems?
Details:
- One LUN is planned with 5 TB of data.
- For the beginning we want to start with 600 Gigabyte for the LUN.
- The LUN is used for database systems.
- We don't want to create a LUN with 5 TB. We want to keep them small, what gives us flexibility in moving storage.
- We are using device-multipathing with two nodes.
- I have created a lvm (with XFS) that gives the flexibility of merging the LUN´s and should allow for expansion in live operation.
About the last point I´m not sure and wanted to ask for other experiences in RHEL8 with GPDB and iSCSI.
