Failed to mount share

I just noticed my drobo shares were unavailable and the shares are now failing to mount. I did a repair on the shares, but it didn’t change anything at all after a reboot. Here is snippet of the error, is this recoverable?

Jan 2 19:54:58 Drobo5N user.crit kernel: [9154108.976036] EXT4-fs error (device sda1): htree_dirblock_to_tree:587: inode #22126801: block 1416102470: comm smbd: bad entry in directory: rec_len % 4 != 0 - offset=0(0), inode=976894005, rec_len=12337, name_len=93

Where are you seeing this error message?
