Bug ID: 265951
Summary: ext2fs: kernel panic when trivial rsync operation from
zfs to ext3 partitions
Product: Base System
Version: 13.0-RELEASE
Hardware: Any
OS: Any
Status: New
Severity: Affects Many People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
When doing rsync trivial (avz) operations from zfs dataset to ext3 partition
mounted with ext2fs.ko module, a kernel panic occurs trashing the whole server.
First UFS filesystem (first disk) is corrupted
Second UFS filesytem (second disk) is corrupted
Ext3fs filesystem (third disk) is corrupted
This is the output of /var/log/daemon.log
Aug 19 07:27:47 myServer savecore[1396]: reboot after panic: ext2_dirbad:
/EXT3-TARGET: bad dir ino 164859907 at offset 0: mangled entry
Aug 19 07:27:47 myServer savecore[1396]: writing core to /var/crash/vmcore.1
- The ext2fs stability and reliability have to be fixed. This is mandatory.
- Perhaps this was improved on the 13.1 branch ?
- Is there a safe way to manage ext3 filesystems regarding kernel panic ?
