Hi, I am experiencing filesystem corruption while using a 1TB (appx.) partition under 4.9-STABLE (sources from Mar 17) and an 8-port 3ware ATA RAID card (twe device driver). The RAID set comprises 5x250GB ATA disks. The kernel logs such messages as: Apr 17 16:25:37 heman /kernel: free inode /clara/170175645 had 137391860 blocks Apr 17 17:18:29 heman /kernel: free inode /clara/169969279 had 1803039330 blocks Apr 17 18:06:38 heman /kernel: free inode /clara/171086221 had 544501359 blocks The operations it was performing at the time involved copying a lot of small (email messages) files from a busy NFS mount to the RAID5 array. A number of processes were all copying different files and the throughput was around 3MB/s to disk. As far as I can tell from sys/ufs/ffs/ffs_alloc.c this error indicates that a kernel data structure contains unexpected data, but I'm not confident enough to be able to tell what might be causing that. After such messages, if I cleanly unmount the filesystem and run fsck, errors are detected. Such errors are: directory corrupted directory contains empty blocks unallocated inode wrong link counts There are many more distinct error messages, but those are the ones I recall. After a number of passes through fsck, the filesystem is eventually marked clean but quite a number of files wind up in lost+found. Has anyone seen behaviour similar to this with twe RAID sets or large partitions in the past? I've not been able to find reports of similar symptoms using Google. Can anyone offer advice on how I might further debug this problem?
