From 9e00163c31676c6b43d2334fdf5b406232f42dee Mon Sep 17 00:00:00 2001 From: Lukas Herbolt Date: Mon, 3 Feb 2025 09:55:13 +0100 Subject: [PATCH] xfs: do not check NEEDSREPAIR if ro,norecovery mount. If there is corrutpion on the filesystem andxfs_repair fails to repair it. The last resort of getting the data is to use norecovery,ro mount. But if the NEEDSREPAIR is set the filesystem cannot be mounted. The flag must be cleared out manually using xfs_db, to get access to what left over of the corrupted fs.
