This issue should be solved by following the below documentation: https://supportportal.juniper.net/s/article/SRX-Commit-failed-with-the-message-error-configjuniper-conf-write-failed-Broken-pipe?language=en_US.
If this procedure doesn't work consider installing a new software image in order to clean the filesystem corruption, consider the methods described on https://supportportal.juniper.net/s/article/SRX-Getting-Started-Junos-Software-Installation-Upgrade?language=en_US.
If the device cannot be recovered and the filesystem cannot be cleaned consider opening a JTAC case and see if a device replacement is needed or if any other procedure can be approached.
