Bug#805252: linux-image-4.2.0-1-amd64: I/O errors when writing to iSCSI volumes
Package: src:linux
Version: 4.2.6-1
Severity: important
Tags: upstream
Dear Maintainer,
with this kernel version writing to iSCSI volumes will consistently
produce I/O errors. It appears as though this happens if a lot of
writes are performed at once (but I'm not sure of that).
I've seen this in the version in unstable (i.e. the version I'm
reporting this against), but also with 4.3-1~exp1, and also with
vanilla upstream git from just now.
Steps to reproduce:
- have an iSCSI target ready (hardware or e.g. targetcli)
- log in to the iSCSI target in a VM or on a separate computer
- dd if=/dev/zero of=/dev/iscsidevice bs=4M
-> will consistently produce I/O errors after a short
amount of time
Reading from the same device is not a problem, I can dd the whole
device to /dev/null without any errors.
For example, the latest testing netinst installer is not able to
install Debian on iSCSI rootfs because of this: when using ext4 as the
root filesystem mkfs.ext4 will fail due to I/O errors consistently,
when using btrfs the filesystem will be created successfully, but the
package installation will fail with I/O errors, presumeably due to a
different block access strategy.
Logs I gathered with the latest upstream git kernel are (when doing
dd if=/dev/zero of=/mnt/foo bs=4M until disk full on a mounted iSCSI
drive):

-----------------------------------------------------------------------------------
The messages are basically the same on 4.2.6-1 on Sid. (The tag # is
not there, but otherwise the output is the same. Note that the sector
numbers for which failures are reported differ when using a filesystem,
but when dd'ing directly to the device, or using mkfs as in the
installer case, they remain the same as far as I can tell.)
The kernel in Jessie is NOT affected, i.e. same Sid userspace with
3.16.7-ckt11-1+deb8u6 works perfectly fine, dd from /dev/zero will work
properly there until the device is full, so I assume this is not an
issue with the target.
(This bug report is done from a sid VM with rootfs on iSCSI that was
upgraded from jessie, otherwise I'd not have been able to install the
VM because of this bug. Since reading from the drive works, I can boot
the VM, but as soon as I try to write larger amounts of data in a short
period of time, the same I/O errors appear. If I just boot and do some
minor things with the system, I don't see any I/O errors and the system
works, But package installations and/or copying of large files can
already trigger the I/O errors, not only my dd example.)
Regards,
Christian
