I made the mistake of ssh’ing into the device and running apt-get update / apt-get upgrade. While I was ssh’d in, I noticed many binaries could not run due to the following error:
libstdc++ "ELF load command alignment not page-aligned"
I realzed too late that I couldn’t SSH in after that, and upon rebooting, got the white light of doom. The funny thing is, SMB was still running, but a port scan revealed that no other services were available. No SSH, no HTTP (hence, no dashboard).
I was able to remove the drive and plug it into my laptop via USB. I’m running archlinux on my laptop. When I plugged in the drive, here’s what the partition scheme looked like:
GPT fdisk (gdisk) version 0.8.10 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. Disk /dev/sdc: 5860533168 sectors, 2.7 TiB Logical sector size: 512 bytes Disk identifier (GUID): 7C725966-C430-432A-B9AE-A0DA9A753C91 Partition table holds up to 128 entries First usable sector is 34, last usable sector is 5860533134 Partitions will be aligned on 2048-sector boundaries Total free space is 31597 sectors (15.4 MiB) Number Start (sector) End (sector) Size Code Name 1 1032192 5031935 1.9 GiB FD00 primary 2 5031936 9031679 1.9 GiB FD00 primary 3 30720 1032191 489.0 MiB 0700 primary 4 9428992 5860532223 2.7 TiB 0700 primary 5 9031680 9226239 95.0 MiB 0700 primary 6 9226240 9422847 96.0 MiB 0700 primary 7 9422848 9424895 1024.0 KiB 0700 primary 8 9424896 9428991 2.0 MiB 0700 primary
My system also automatically provisioned the RAID1:
$ dmesg | grep raid1 [275859.614738] md: raid1 personality registered for level 1 [275859.614963] md/raid1:md127: active with 2 out of 2 mirrors $ ls -l /dev/md total 0 lrwxrwxrwx 1 root root 8 Aug 2 01:40 1_0 -> ../md127
I mounted /dev/md127, and confirmed that this was the root filesystem. So, I downloaded the latest firmware from here, and extracted the rootfs.img. I then used dd to write the image to /dev/md127:
$ sudo dd bs=32M if=rootfs.img of=/dev/md127
I double checked that /dev/md127 could mount successfully and was able to verify that the new filesystem was there and in-tact.
Unfortunately when I rebooted the MyCloud device it still had the white light, and this time I couldn’t ping it at all. I let it run overnight (in case it was doing a disk check or something) with no luck. Any ideas on what I need to do to get the rootfs installed/bootstrapped correctly?
