[gentoo-user] Need help: Filesystem (ext4) corrupted!
Hi, I need some urgent help... The rootfs and $HOME of my embedded system is stored on a 16GB SD-card (about 5GB used, rest free). The FS is ext4. Since the system hangs for unknown reasons several times I removed the sdcard, put it in a card reader and did an ext4.fsck on it. Clean was the result. Then I forced a check with -f -p. The result was: solfire:/rootfsck.ext4 -f -p /dev/sdb2 rootfs: Inodes that were part of a corrupted orphan linked list found. rootfs: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY. (i.e., without -a or -p options) [1]18644 exit 4 fsck.ext4 -f -p /dev/sdb2 Return code 4 means 4- File system errors left uncorrected which indicates nothing and all at the same time. At this point I started to write this mail. Before I fscked the sdcard I mounted the FS and tar'ed everything on it into a backup file. The tar process did not return an error. Since it costs A LOT OF TIME to compile everything from source on a 1GHz CPUed embedded system natively - and for abvious different other reasons - I am very interested in doing the next steps correctly. What can I do to eliminate the problem without data loss (best case) or to save the most while knowing what and where the corrupted data are located on the system? Thank you very much in advance for any help! Best regards, mcc
