That's an error on sdc all right.
[ 2.875478] Buffer I/O error on device sdc1, logical block 1
Note that this refers to sdc1, the first partition on sdc.
cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5]
[raid4] [raid10]
md0 : inactive sdb1[0](S) sde1[3](S) sdd1[2](S)
5860147464 blocks super 1.2
Note that this is again referring to *partitions* (sdb1, sde1, sdd1),
not the whole disks. So your faulty RAID member is *sdc1* (not sdc).
Below running mdstat for sdc. Checking sdb, sdd, sde appear fine.
mdadm --examine /dev/sdc
/dev/sdc: MBR Magic : aa55
Partition[0] : 3907027120 sectors at 2048 (type fd)
That's expected. sdc isn't a RAID device.
mdadm --examine /dev/sdc1
mdadm: No md superblock detected on /dev/sdc1.
That's not good (but we already knew that the drive is unhappy).
Is there other information needed to determine the issue? Where do I
go from here?
What does mdadm --detail /dev/md0 say?
