You can run tests with the special test script. The script can be created with any text editor or by executing the following command:
| Code Block |
|---|
ztest@zone:~# cat > z.sh <<EOT #!/bin/bash LOG="/var/tmp/zfstest.\$(date +%F-%T).txt" ipa=\$(sudo ifconfig | grep -A 1 vmxnet3s0 | sed '1d; s/^[ \\t]*inet[ \\t]*//; s/[ \\t]*netmask.*\$//') sudo /sbin/zpool destroy testpool sudo -E /usr/sbin/svcadm disable -s svc:/system/fmd:default sudo -E find /var/fm/fmd -type f -exec rm {} \\; sudo -E /usr/sbin/svcadm enable svc:/system/fmd:default # we need 3 x 8G drives with 512b sector size export DISKS="\$1 \$2 \$3" export KEEP="rpool data" export ZFS_USE_ONLY_DISKS=yes #remove partition on disks for D in \$DISKS

After running of this script you will find the log in the /var/tmp/zfstest.<ISO TIME>.txt file. It will contain information in the format that is used in Test Results.
Before running of this script you have to get IDs of tree 8-GB disks from this VM. You can do it with the diskinfo command and run the test script with these IDs in parameters (you can find IDs in the DISK column of the diskinfo output), for example:
...
Then you can disconnect in any time by pressing Ctrl-A d and connect back in the new SSH session by the command:
ztest@zone:~# screen -r
6. Run in stability mode
Tests (that are prepared according instructions in the previous section) could be run in the stability mode. To do this just copy this script to the, let say, stab_zfs.h file and make it executable or do these commands:
| Code Block |
|---|
cat > stab_zfs.sh <<EOT
#!/bin/bash

if [[ \$num -gt 2 ]]; then
(( delta += \${tm[2]} ))

}

The test script could be run in 3 modes:
for a specific number of iterations
In this case you have to put the -i option and enter the number of iterations, for example, to set 10 iterations:
| Code Block |
|---|
screen ./stab_zfs.sh -i 10 |
to work for the specific period of time
In this case you have to put the -d option and enter the time duration in the HH:MM[:SS] format, for example, to work for 10 hours and 15 minutes:
| Code Block |
|---|
screen ./stab_zfs.sh -d 10:15 |
or, for example to work for 20 seconds:
| Code Block |
|---|
screen ./stab_zfs.sh -d 00:00:20 |
and finally to stop at the specified date and time
In this case you have to put the -t and enter the date and time of stop in the HH:MM[:SS] [DAY-MONTH_YEAR] format, for example, to work from the start to 17:00 of 8th of August 2023 year you will enter:
| Code Block |
|---|
screen ./stab_zfs.sh -t 17:00 8-AUG-2023 |
If date is omitted, and only time is entered, it’s supposed that date is the current one. I.e. to stop today at 19:00 you will enter:
| Code Block |
|---|
screen ./stab_zfs.sh -t 19:00 |
...
After the script is finished common log will be put to the /var/tmp/stabzfs.<ISO TIME>.txt file. Logs for every separate pass will be created according the previous section.Running in stability mode
