FSCK Fails after expansion on NVX case# 20304759
I have an NVX that has given me some FSCK problems lately. It started with an expansion months ago that caused FSCK failures, so all the data was backed up, the NVX reset and rebuilt, and then all the data restored.
Subsequently, new online FSCK failues were found. Rebooting with FSCK enabled took the data volume offline and tech support was unable to fix the problem. I managed to mount the volume read-only and back the data up and reinitialize again.
In my latest attempts to reset and rebuild the box, I decided to be extra paranoid. After the initial 4T volume was built, I was informed that a volume expansion would take place on the next reboot (expected). So I decided to force an FSCK on reboot. That one came back clean. After the additional 1TB of space was added to the volume (Bringing the volume to a 5099GB size), I was informed again that a volume expansion would take place on the next reboot (expected). I forced an FSCK on reboot and rebooted the NVX. Now it's come back with errors and the data volume is offline. FSCK errors with a memory allocation failure. I'm somewhat convinced that something in 4.2.22 is misbehaving when expanding the volume, corrupting large numbers of inodes to the point that it exhausts all memory on the system.
Also note that I've run the boot menu's Test Disks without any issues.
Anyone have any ideas on how to resolve this? The fact that an empty data volume is coming back with FSCK errors is rather impressive.

- Hi guys, we upgrade the ext2/ext3/ext4 file system utilities - e2fsprogs in 4.2.23 T build, so it's fixed now. Please do not expand volume in 4.2.22. Just wait 4.2.23.
And the bug is only in NVX, 32 bits system. Ultra & Pro serials, 64 bits system have no problem.
Thanks.

Well, that's good news that the bug is fixed in 4.2.23.... but, what about those of us that didn't know the bug existed and expanded already? Am I just SOL here or is there a recovery procedure/process support can help us through?
This is a royal pain for me right now as I know have an unusable array and users have been down without their files all day!!
