'zpool scrub' should tell you if the filesystem is corrupted. Time to replace the drive. You should be able to convert the vdev that contains the failing drive into a mirror temporarily, and sync the data without downtime beyond maybe a few reboots to install the new disk (assuming you have space to plug the new drive in without unplugging any of the old ones). Failing that, you're going to need to rebuild the zpool from scratch and restore your data from backup. Also, the fact that you have how ever many terabytes of data with no resilience just makes me feel on edge -- and it's not even my data. Strongly recommend rebuilding your zpool as a RAIDZ of 8 drives -- yes, you'll end up with less usable space, but you and your data will survive failure of a drive and a 'zpool scrub' will be able to fix things even if a bad spot on one drive has scrambled some of your data. --wtmDRLdxu3jgTk8DGUNq88N4HTkBmf4lA-- --u4XCUfLFKGwU4U1k02eQMoQJsrp8xMPCS Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQJ8BAEBCgBmBQJXolBMXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NTNBNjhCOTEzQTRFNkNGM0UxRTEzMjZC QjIzQUY1MThFMUE0MDEzAAoJELsjr1GOGkAT0jIP/iZ/7nZ/IplID4ajSYFZ469y xX7Yibm3sCeHB/NQ1vt6Fai+k1kjgkKaVcji5QOGNraGO5ogIcWsYVPa+byMjS1z 9Z6bTOhmcboPuPJ1t+VYmTgzutW9aKHNp21nOjZvWbCNRBQ12kipEudtWECcpsdH pu3nb1DOrd3CySvk7K8lA2NLTzP4RSvD7MlhtJhbFElrHvAxYzcyLFkJeHtlf9TS kQ2EdOVgkGw/uoUthQtDRXk0s2iXdYj/9h0pWoQJGf6oLJazMa7Xx2ELNmAdQZfV nYSuGzT+ZBmYifFo2TuKssjEbmJ78LxTKb61TdOtbYNDM5a/eY0weDQlN1Q7FRB5 u8mzWiszOMCoGZW+SlV6CJPYfQIJJe9kXlbWZ38s27/vBemC7LtwG4pgUwtsN//M yy4m5Wnf4DNjP34saB4aSiCoHIzqgwrXYTigd4kBUM1rGT/X1erWlrdx1YFBIGQJ guiPTN9eVn2iKehh4ayZCNcoryPlNuV6gPuwuCAmrB1zZsP4ZU50wkOGWycMtBfa p4Azq3aaLR11kjPWQupmXoMq+iX0we8Ix9oF/3tRlwur4IdOyY8OWp+12QISdw6g M7Eajn2UIBVHvgw9zhj/bxz9rkZAOdohcGaAPIV0zxh5ejWcj03CM4w0UI4PcHku 5DvR5shWc/BMy6CAWtdP =PSkx -----END PGP SIGNATURE----- --u4XCUfLFKGwU4U1k02eQMoQJsrp8xMPCS--
