Firmware upgrades on Dell servers failing

tmp folder issues

[morten]

Hello,

On our Dell servers running Cloudlinux we cannot upgrade the firmware because of writing permissions to tmp folder.

Doing a upgrade:
sh ./Power_Firmware_KCGDJ_LN_07.15.7F.BIN
/tmp/Power_Firmware_KCGDJ_LN_07.15.7F.BIN-593814-10472/spsetup.sh: line 723: ./dupdisneyinstall.sh: Permission denied
/tmp/Power_Firmware_KCGDJ_LN_07.15.7F.BIN-593814-10472/spsetup.sh: line 727: ./dupdisneyinstall.sh: Permission denied
/tmp/Power_Firmware_KCGDJ_LN_07.15.7F.BIN-593814-10472/spsetup.sh: line 1920: ./getSystemId: Permission denied
ldd: warning: you do not have execution permission for `./sputility.bin

Inventory collection failed.

On our CentOS servers its working fine.
How can we get this fixed?

Hello,

This is very strange issue. Do you run the Power_Firmware_KCGDJ_LN_07.15.7F.BIN as root user? cloudLinux should not affect root user at all.

Also please make sure that /tmp is not mounted with noexec flag.

[morten]

Yes, running as root user.
Have tried different firmware upgrades on different servers.

How would I check if it is mounted with noexec flag? Should it not be that? I think all servers are that as standard.

Hello,

Runnig # mount |grep tmp should return something like

/usr/tmpDSK on /tmp type ext3 (rw,noexec,nosuid,loop=/dev/loop0)
/tmp on /var/tmp type none (rw,noexec,nosuid,bind)

Im pretty sure that issue is related to noexec flag.

hi

from experience running this:

mount -o remount,suid,exec /tmp

then

update_firmware --yes

will fix the issue. When it reboots, the mount will return back to its original state on /tmp

the linux dell vault for updating dell firmware is quite dated too, ie it still uses older firmwares for drac/nics/lifecycle controller etc.
