whats the number of times the letter w appears in:
q: rhel 7 server no longer successfully boots and i cant determine exactly why the server disks are configured as follows:
/dev/sda, /dev/sdb, /dev/sdc, /dev/sdd are zfs zraid2 (using zfs on linux)
/dev/sde1 is xfs /boot partition. /dev/sde2 is swap. /dev/sde3 is btrfs (holds everything else).
i rebooted my server after updating a few packages, including zfs. now, when it boots, it goes to the grub selection menu as normal, but it hangs after that on any of the four options (three kernels choices and a recovery option).
i cant copy text but i did take pictures of where its hanging (shown below). i thought maybe the problem was with zfs since i updated that just before rebooting, but ive updated zfs before with no problems so i think that might just be a coincidence. i do see btrfs errors in both though, so i think thats where the problem is. unfortunately i dont really know much about btrfs, i originally just chose it because id never used it before and i wanted to see if i noticed any difference from ext4.
i dont really know what to do at this point to make things work again without risking data loss on my zpool, so i thought id ask you guys here for suggestions. im hoping theres a quick and simple fix i can implement.
when booting any of the three regular kernel options

when booting the recovery option:
