Hello, we have a virtual machine running linxu-4.1.11 on VMware ESX. After swapping hard disks on the host the VM mounted its root file system read-only two times now after detecting some file system corruption. I hopefully collected enough data from the system, which I attach to this mail. Looking at the ACL block I don't see the EXT4_XATTR_MAGIC. But I see the string signature of two EAs ("posix_acl" and "DOSATTRIB"), so block 14221335 seems to be a corrupted ACL block. We recently observed several other problems related to EAs, so here for reference: * With 3.16 we had on corruption on KVM. I re-checked , which is fixed since v3.17-rc1~141^2~79, so this is a different bug. And here we're running on VMware. * With 4.1.11 we observed samba hanging due to many different EAs: - Here smbd doesn't get stuck, but the fs gets mounted read-only. * There is , which has "ext4_xattr_block_get" in it, but is with 4.5. Any ideas? Philipp PS: I'm subscribed to LKML but not to ext4. -- Philipp Hahn Open Source Software Engineer Univention GmbH be open.
