Thank you Heisath and Werner for your help. It was something in my tmp folder that was growing. Nuked it and now everything is back to normal.

Just to add to this I am able to locate the emmc drive through df command but i um unable to access it.. please see below Filesystem 1K-blocks Used Available Use% Mounted on udev 1901936 0 1901936 0% /dev tmpfs 395612 7400 388212 2% /run /dev/mmcblk2p1 14843200 13393004 1268104 92% / tmpfs 1978044 0 1978044 0% /dev/shm tmpfs 5120 0 5120 0% /run/lock tmpfs 1978044 0 1978044 0% /sys/fs/cgroup tmpfs 1978044 4 1978040 1% /tmp folder2ram 1978044 103360 1874684 6% /var/log folder2ram 1978044 0 1978044 0% /var/tmp folder2ram 1978044 772 1977272 1% /var/lib/openmediavault/rrd folder2ram 1978044 728 1977316 1% /var/spool folder2ram 1978044 16748 1961296 1% /var/lib/rrdcached folder2ram 1978044 4 1978040 1% /var/lib/monit folder2ram 1978044 1604 1976440 1% /var/cache/samba /dev/md0 11627192048 1934573924 9692601740 17% /srv/dev-disk-by-uuid-72c7802e-29b2-406a-81b6-0323b18e6ef3 tmpfs 395608 0 395608 0% /run/user/0 root@helios64:~# /dev/mmcblk2p1 -bash: /dev/mmcblk2p1: Permission denied

Thank you for your suggestion for that have installed ut and tried running it using ncdu -e ncdu -x however cant find anything apart from system files is there any other commands that i should try.

My Helios has been running well for the most part stable for the past few weeks however last night i noticed when looking at my file systems in omv that my 14 GiB eMMC drive which houses my ambian install is at 13.13GiB and looks to be growing. Normally this sits around the 5 GiB. I have checked my docker install for anything suspicious but my plex docker is only taking up about 400mb. looking at my system logs i am getting a repeated this error which is new and might be related however i am not really sure what program is casing it.

followed that link as best i could (pretty new to this) and got the following [Sat May 22 13:31:33 2021] md/raid0:md0: cannot assemble multi-zone RAID0 with default_layout setting [Sat May 22 13:31:33 2021] md/raid0: please set raid0.default_layout to 1 or 2 any advice on what i should do?

hi all. I recently updated my Kurnel and rebooted my Helios64. when it loaded in to OMV i noticed my raid drive is missing. i can still see the disks just not the raid drive . Checking on the array i can see it failed with an error 524. Would love some suggestions on how to repair the array. below is the details i was able to get,.. sorry for the large info dump root@helios64:~# mdadm --run /dev/md0 mdadm: failed to start array /dev/md0: Unknown error 524 root@helios64:~# mdadm -D /dev/md0 /dev/md0: Version : 1.2 Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Total Devices : 4 Persistence : Superblock is persistent Update Time : Mon Dec 14 16:49:07 2020 State : active, FAILED, Not Started Active Devices : 4 Working Devices : 4 Failed Devices : 0 Spare Devices : 0 Chunk Size : 512K Consistency Policy : unknown Name : helios64:Home (local to host helios64) UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Events : 0 Number Major Minor RaidDevice State - 0 0 0 removed - 0 0 1 removed - 0 0 2 removed - 0 0 3 removed - 8 32 0 sync /dev/sdc - 8 0 2 sync /dev/sda - 8 48 1 sync /dev/sdd - 8 16 3 sync /dev/sdb root@helios64:~# ^C root@helios64:~# cat /proc/mdstat Personalities : [raid0] [linear] [multipath] [raid1] [raid6] [raid5] [raid4] [raid10] md0 : inactive sdd[1] sdc[0] sdb[3] sda[2] 19534553088 blocks super 1.2 unused devices: <none> root@helios64:~# mdadm --examine /dev/sd[abcde] /dev/sda: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Name : helios64:Home (local to host helios64) Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Avail Dev Size : 11720780976 (5588.90 GiB 6001.04 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 4efe5ed4:e612db01:c827abcf:30cf9d60 Update Time : Mon Dec 14 16:49:07 2020 Bad Block Log : 512 entries available at offset 8 sectors Checksum : 403cbc68 - correct Events : 0 Chunk Size : 512K Device Role : Active device 2 Array State : AAAA ('A' == active, '.' == missing, 'R' == replacing) /dev/sdb: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Name : helios64:Home (local to host helios64) Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Avail Dev Size : 11720780976 (5588.90 GiB 6001.04 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 2fa13dfd:7e1c90cc:e086e232:a2f84f2a Update Time : Mon Dec 14 16:49:07 2020 Bad Block Log : 512 entries available at offset 8 sectors Checksum : 60b9f16c - correct Events : 0 Chunk Size : 512K Device Role : Active device 3 Array State : AAAA ('A' == active, '.' == missing, 'R' == replacing) /dev/sdc: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Name : helios64:Home (local to host helios64) Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Avail Dev Size : 7813772976 (3725.90 GiB 4000.65 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 4cee06fa:a32a5035:df544d4a:9a37139a Update Time : Mon Dec 14 16:49:07 2020 Bad Block Log : 512 entries available at offset 8 sectors Checksum : 649123a1 - correct Events : 0 Chunk Size : 512K Device Role : Active device 0 Array State : AAAA ('A' == active, '.' == missing, 'R' == replacing) /dev/sdd: Magic : a92b4efc Version : 1.2 Feature Map : 0x0 Array UUID : bc34df85:c451fddc:fdc99dec:5400a7bb Name : helios64:Home (local to host helios64) Creation Time : Mon Dec 14 16:49:07 2020 Raid Level : raid0 Raid Devices : 4 Avail Dev Size : 7813772976 (3725.90 GiB 4000.65 GB) Data Offset : 264192 sectors Super Offset : 8 sectors Unused Space : before=264112 sectors, after=0 sectors State : clean Device UUID : 52c35a71:983beb7b:eeae2343:83e9fa0f Update Time : Mon Dec 14 16:49:07 2020 Bad Block Log : 512 entries available at offset 8 sectors Checksum : 913e1594 - correct Events : 0 Chunk Size : 512K Device Role : Active device 1 Array State : AAAA ('A' == active, '.' == missing, 'R' == replacing) root@helios64:~# mdadm --stop /dev/md0 mdadm: stopped /dev/md0 root@helios64:~# mdadm /dev/md0 --assemble /dev/sd[abcde] mdadm: failed to RUN_ARRAY /dev/md0: Unknown error 524 root@helios64:~# mdadm /dev/md0 --assemble --force /dev/sd[abcde] mdadm: /dev/sda is busy - skipping mdadm: /dev/sdb is busy - skipping mdadm: /dev/sdc is busy - skipping mdadm: /dev/sdd is busy - skipping root@helios64:~#

Thank you both for your quick replies. I switched to Linux Kernel: 4.4 and was able to access the network. I have checked network status on OMV and i am running at 1000Mbit. It is good to know that I am not the only one with a lack of a green flashing light and that my unit isn't broken.

HI all I just received my Helios64 and built it this weekend. I followed the instruction and everything was going well. After installing OMV i tried to access it via the network and realised that my unit wasnt connecting over lan. I have tried both ports on the back and i am unable to connect just get the flashing orange light (no green light). I have tried using different cable and different ports on the router, a network restart, system restart but noting. If anyone can offer a suggestion of what else to try it would be appreciated.
