You can mount again /gluster1/data (don't forget SELINUX) and then use gluster's reset-brick to rebuild that brick.
Most probably you have an entry that was saved on hydra4:/gluster1/data and the arbiter but was not pushed to the surviving brick (based on the entry in the arbiter)
Usually, I use method 2 from https://docs.gluster.org/en/latest/Troubleshooting/gfid-to-path/ to identify the file and then you can check the status of that file on the bricks (and if necessary restore from backup). You should do that only after you have brought back hydra4:/gluster1/data to the volume.
You should also reconsider the brick layout, as in some cases a single hydra failure (whole server) will kill a subvolume and all VMs' disks on that subvolume will be unavailable.

did some more digging into the heal info output.
Found also the following:
[...] Brick hydra4:/gluster1/data Status: Transport endpoint is not connected Number of entries: - Brick hydra3:/arbiter/2 <gfid:2aa223b0-77f5-441e-bc76-34c8d459eeaa> [...]So, to augment what I wrote before, the errors appear in "Brick hydra3:/gluster3/data" and "Brick hydra3:/arbiter/2", plus that "Transport endpoint is not connected" for "Brick hydra4:/gluster1/data".
I need to add that hydra4:/gluster1 is the RAID that had major hardware failure.
