    Default Server hangs every few days

    Hello,

    Got a problem with a open -e dss 6 lite setup (latest version).

    Every few days the machine hangs, it does respond to pings, but no web admin. Also the console is not accessible.

    Hardware setup:

    Supermicro 16 disk chassis.
    Supermicro X8DTN+-F + Intel xeon 5620
    Areca 1880 controller
    6x 2TB WD Raid Edition disks in RAID 50 configuration


    I've checked the logs but apart from some warnings i cannot find the cause of the hang. Which logfiles should i check?

    Thanks

    Test with another USB flash stick with DSS on it, also check the critical error logs and the dmesg2 logs.
    All the best,

    DSS is currently running from a Intel 40GB SSD.

    In the logs the only errors i found are:

    Code:
    dev_vdisk: Registering virtual vdisk_blockio device S5iAcDpDBwN6nolN (WRITE_THROUGH, BLOCKIO)
    dev_vdisk: ***ERROR***: blkdev_issue_flush() failed: -95
    dev_vdisk: ***WARNING***: Device /dev/vg+backup1/lv+b+lvbackup101 doesn't support barriers, switching to NV_CACHE mode. Read README for more details.
    dev_vdisk: Attached SCSI target virtual disk S5iAcDpDBwN6nolN (file="/dev/vg+backup1/lv+b+lvbackup101", fs=768000MB, bs=512, nblocks=1572864000, cyln=768000)
    scst: Attached to virtual device S5iAcDpDBwN6nolN (id 1)
    and

    Code:

    nothing else i checked pointed to an error.

    look into critical errors log, and dmesg logs as mentioned.
    If you can provide them to me, I'll take a look.

    also look at the iSCSI folder and show me the target settings.

    Hello,

    I have uploaded the logs here: logs. I couldn't find any errors in the logs, maybe you can take a look.

    Thanks
