NAS326 defaults after restart or shutdown
NAS326 after reboot or shutdown defaults all settings and passwords etc.
Every time after reboot or shutdown I need to set new password and set it up again and again.
Is this by design behavior or there is solution?
I must admit that I don't know much about ubi's. One of the blocks is in the middle of your config partition:nand_read_bbt: bad block at 0x0000004400000x000000400000-0x000000e00000 : "Config"but I don't know if the filesystem on config should be able to handle that. Bad blocks in nand are normal, and somehow it's handled, but I don't know if a bad block on any place can be handled.If the 'reset_and_reboot' script (executed as root!) doesn't solve your issue, and you box is still under warranty, I'd RMA it.
That is not by design. The configuration should be stored on a flash partition. If that fails, then the configuration is stored on the mountpoint of that partition, which is on a ramdisk, and so volatile.It might help to do a factory reset (press the reset button on the back for 25 seconds, until it has beeped 3 times), which puts a new filesystem on that partition.0
Unfortunately factory reset didn't help.When I look into dmesg I found some information about NAND bad blocks:--------dmesg cut--------------armada-nand f10d0000.nand: Initialize HAL based NFC in 8bit mode with DMA Disabled using BCH 4bit ECC

-------dmesg cut-------Could it be the reason?
I had to RMA it. Replacement device has 7 bad blocks in nand, but at least it saves configuration. Thank you!0
