---


Disabling NCQ (troubleshooting mode)

echo 1 > /sys/block/sdX/device/queue_depth

where X is the problem drive

--

Disabling NCQ permanently for each boot (for problematic chipsets)

nano /etc/default/grub
change

GRUB_CMDLINE_LINUX=""

to

GRUB_CMDLINE_LINUX="libata.force=noncq"

Ctrl+S
Ctrl+X
update-grub
reboot

--

Force SATA data link speed permanently for each boot (for problematic chipsets)

nano /etc/default/grub
change

GRUB_CMDLINE_LINUX=""

to

GRUB_CMDLINE_LINUX="libata.force=xGbps"
for x = 1.5, 3.0, 6.0

Ctrl+S
Ctrl+X
update-grub
reboot

--

Override default journal data behavior for ext4 filesystems on a device


nano /etc/fstab

on the mount entry in question, add one of the following in the options
section:
data=journal
data=ordered
data=writeback


Note: data=ordered is the default in most distros.

--

Permanently change the default journal behavior for ext4 filesystems on a
device


tune2fs -o journal_data /dev/[mdX,sdX]
tune2fs -o journal_data_ordered /dev/[mdX,sdX]
tune2fs -o journal_data_writeback /dev/[mdX,sdX]


Note: journal_data_ordered is the default in most distros.

--

SSH terminal fix for certain SSH clients


On the physical NAS, type the following:
apt-get install ncurses-term

--

Enabling nmbd for NETBIOS discovery (starting with OpenMediaVault 6.0.19)

As of OpenMediaVault 6.6.0, this entry is obsolete with the 'Enable NetBIOS'
setting located in Services > SMB/CIFS > Settings, under Advanced Settings.


systemctl unmask nmbd.service
omv-env set OMV_SAMBA_NMBD_ENABLE "YES"
omv-salt stage run prepare

omv-salt stage run deploy
OR
omv-salt stage deploy run samba

--

SMB: extra options

As of OpenMediaVault 6.8.0, the min protocol entry is obsolete with the 'Minimum
protocol version' setting located in Services > SMB/CIFS > Settings, under
Advanced Settings... to a point. If you need Win3.x to Win9x support, you still
need the server min protocol=LANMAN1 entry under Extra options.


server min protocol=LANMAN1 (for Win3.x to Win9x machine support at minimum)
OR
server min protocol=NT1 (for NT4 to WinXP machine support at minimum)

netbios name=xyz (this does not seem to work right)

--

WSDD: hostname change (this also does not seem to work right)


omv-env set OMV_WSDD_OPTIONS "-h xyz"
omv-salt stage run prepare

omv-salt stage run deploy
OR
omv-salt stage deploy run samba
