I become the following problem on _3_ different GSM7212 switches shortly after another:
The switches are running long time without any problem. When saving the config with 'save' the saving seems not successfull - telnet sessions hangs and it's not possible to remote login any more.
2 of these switches could be recovered through an hard restart (power off/on).
1 of these switches could not be recovered. This switch starts with lots of warning messages on the serial console that the flash file system is corrupt and one should reformat it (or anything like that, the messages scrolled so fast that I can't remember exactly). Cuirios is, I can give this gsm7212 a new config via console and it runs as long I do not save the config.
What is the procedure to recover such an corrupt flash filesystem ?
Today the 4'th switch (same model) got the same problem. All of them are now 3.5 years old and I fear, sooner or later all of our GSM7xxx NetGear Switches will come in the same trouble.
Trying to get phone support was senseless, because nearly an hour their support number was busy. We will make RMA's for all of them. I'm not glad of this - these are relative expensive Business Switches. In future setups we will go back to Cisco Switches if this trouble goes on. Price is not the only criteria.
