Title:
Areca ARCMSR Driver hangs under heavy load
Status in “linux” package in Ubuntu:
Invalid
Bug description:
ARCMSR driver which is included in the linux-image-2.6.24-26-server
image (version: Driver Version 1.20.00.15 2007/08/30) aborts device
commands under heavy load (easy method to trigger would be with
xfs_fsr with a lot of drives (shows up here with large arrays of 60+
drives)).
Below is an example (two areca controllers, each has 4 luns/32 drives;
the controller in this case controlling the second batch of 4 luns
starts aborting commands and freezes).
This causes file system corruption and data loss.
A new driver was produced which can be obtained at:
ftp://ftp.areca.com.tw/RaidCards/AP_Drivers/Linux/DRIVER/SourceCode/arcmsr.1.20.0X.15-90605.zip
I have been running this new driver for the past 2-3 days with no
recurrence, so it's an improvement. This should be back-ported to the
kernel to avoid data corruption issues.
[attached is system heuristic information as well as output of sysrq
when aborts happen for reference).
