Summary0015568: Dell 2650: percraid aacraid = disaster: 'Host adapter reset request. SCSI hang ?' + 'rejecting I/O to offline device' : NO '/'
DescriptionWith CentOS 7.5.1804 AltArch (i686) installed on an old Dell E2650 rackmount server,
an Intel i686 2x3ghz (4-core) i686 machine,
with 2 RAID-1 mirrored 38GB disks + 1 mirror duplicate 'Failover Disk',
having chosen the 'BTRFS' anaconda installation option (I wish I hadn't now) ,
the OS continually crashes after some heavy disk activity (eg. unpacking a large
tar file), with the error shown at the end of the attached dmesg.log file.

The BTRFS '/' (/dev/sda3) and XFS '/boot' /dev/sda3 filesystems then become
inaccessible - all accesses to uncached files fail with an 'Input/output error'
in the logs.

Happily, when this happened the last time, the 'emacs' program was
cached, so I was able to scroll through the dmesg.log created with:
  $ cd /tmp
  $ dmesg > dmesg.log
Of course, there is nothing I can do this file on the still working tmpfs,
except use a CACHED program :
  $ scp dmesg.log $anywhere
  -bash: /usr/bin/scp: Input/output error
But, since I was just using emacs:
  $ emacs dmesg.log
worked OK.

So here are the excerpts from that log, showing initialization
and the messages that were emitted when the problem occurred:


$ dmesg > /tmp/dmesg.log

Then there are >1700 repetitions of the last message -
no access to any uncached files from the /dev/sda3 filesystem
is now possible.

I have tried :

  o Removing the 'Failover Disk' from the Dell RAID Controller BIOS Configuration
   
  o Swapping the Mirror Disk with the Failover Disk
     (The DELL RAID BIOS then rebuilds the mirror successfully).

  o Removing the Mirror #1 Disk And Failover Disks, and
     booting with one Boot Disk -
     
     - Booting with just the Mirror #1 Disk

     - Booting with just the Failover Disk

     - Booting with just what is ordinarily the Boot Disk / Mirror #0

It looks like the modern version of the linux 'aacraid' module
is having problems with the OLD adaptec SCSI controller
on the DELL 2650 (> 10 years old, but otherwise nothing wrong with it,
and quite fast (>3ghz)).

PLEASE HELP - any suggestions gratefully received.
  



Steps To ReproduceRun latest version of kernel on old DELL E2650 with hardware RAID enabled -
the SCSI controller suffers a fatal error condition and does not recover.
