Extended LVM on iSCSI won't write to extended storage
by mschaffner9239 from LinuxQuestions.org on (#6K7Q2)
Debian 12 -
Originally setup an iSCSI mount to 4 LUNS at 5TB for each LUN. The 4 LUNS have been formatted as GPT and then LVM created to make those 4 LUNs as one Logical Volume. When that storage was getting close to full, allocated 2 additional LUNS at 5TB for each. Partitioned each of the new LUNs that same and added them into the Logical Volume. Ran xfs_growfs to expand the file system with the additional storage. Now when writing to this LVM when the space used hits the 20TB of the original 4 LUNs it stops writing to the LVM. I'm sure it has something to do with the XFS filesystem, but unable to run xfs_repair as it runs out of memory before it completes, and I'm unable to allocate any additional memory to the system.
Any suggestions on how to get the system to write to the additional storage that has been added to the LVM?
