Not enough free space to upload VxRail update

As you probably know, I like the VxRail HCI concept. Yet there is one point in my opinion that can still be improved.
Sometimes a log must also be generated for support purposes in a VxRail cluster. After creating a new log bundle it can be downloaded but not deleted with the result that these logs remain on the VxRail manager (VxRm). Not a problem in itself but it has often happened to me that not enough free space is available while uploading the new VxRail code. The example below shows that “/dev/sda3” is 80% full.

vxrm:~ # df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 3.9G 0 3.9G 0% /dev
tmpfs 3.9G 4.0K 3.9G 1% /dev/shm
tmpfs 3.9G 393M 3.6G 10% /run
tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup
/dev/sda3 16G 7.6G 8.1G 80% /
/dev/sda1 124M 39M 80M 33% /boot
/dev/mapper/data_vg-store1 2.0G 3.1M 1.9G 1% /data/store1
/dev/mapper/data_vg-store2 14G 9.3G 3.8G 72% /data/store2
tmpfs 850M 0 850M 0% /run/user/123
tmpfs 850M 0 850M 0% /run/user/4000

The following command finds temporary large files that are usually left behind after an update or generating a support log bundle. Always take a snapshot before make any change.

Find /tmp -type f -size +20000k -exec ls -lh {} \; | awk ‘{ print $9 “: ” $5 }’

Check the output and delete the large files in “/tmp”. As can be seen in the overview below, “/dev/sda3” is now filled up for only 52%. This is more than enough to upload the VxRail update.

vxrm:~ # df -h
Filesystem Size Used Avail Use% Mounted on
devtmpfs 3.9G 0 3.9G 0% /dev
tmpfs 3.9G 4.0K 3.9G 1% /dev/shm
tmpfs 3.9G 393M 3.6G 10% /run
tmpfs 3.9G 0 3.9G 0% /sys/fs/cgroup
/dev/sda3 16G 7.6G 8.1G 52% /
/dev/sda1 124M 39M 80M 33% /boot
/dev/mapper/data_vg-store1 2.0G 3.1M 1.9G 1% /data/store1
/dev/mapper/data_vg-store2 14G 9.3G 3.8G 72% /data/store2
tmpfs 850M 0 850M 0% /run/user/123
tmpfs 850M 0 850M 0% /run/user/4000

My conclusion is that I prefer a download stream of the support log bundle instead of placing the file on the VxRail Manager. Maybe in a future release?

The above is just an example. It’s at your own risk to make any changes. You can always log a support case at Dell Support if you encounter this issue.

  1. TRhe correct command line is:
    find /tmp -type f -size +20000k -exec ls -lh {} \; | awk ‘{ print $9 “: ” $5 }’
    (without the automatic format from Word)
