Hi all ,
readiness check failed because of no enough space in the root partition.
checking the logs , the installation need about 5go in the root partition that can't provide due to its size ( 3.7go)
infos :
upgrade from FMC 6.2.2.1
Firepower 2130
logs :
ui:[52%] Fatal error: Fatal error: Not enough root disk space available. You need at least 5747712K free to perform this upgrade. You have 2416488K free.
