FreeNAS: FreeNAS 8.0.1-RC2 AvailableFreeNAS 8.0.1-RC2 Available
FreeNAS 8.0.1-RC2 has been released. From the Release Notes:
This is Release Candidate 2 for FreeNAS 8.0.1....hopefully the last stepping stone to FreeNAS 8.0.1-RELEASE.
*** IMPORTANT ***
The image size increased in 8.0.1-BETA3. The new size requires a 2 GB storage device. The GUI upgrade can be used to upgrade a system from BETA3, BETA4, or RC1 but upgrades from earlier releases can only be done from the CD. The other option is to save the config, reinstall the new version, then restore the config.
Major changes:
- The mail subsystem has been rewritten due to major interop issues with the previous implementation of the mail subsystem and various mail server setups (including gmail). This was done by removing msmtp and replacing it's functionality with python code. (r7756, r7757, r7758 )
- The iSCSI target daemon (istgt) has been updated to address interoperability issues with VMWare ESXi 5.0 (r7530, r7652, r7817)
Changes since 8.0.1-RC1
- Fix a bug where a failed upgrade after a config was uploaded was resulting in the system "reverting" to using the uploaded config instead of the previous running config. (r7535)
- Save config now uses a hostname/date combo in the file name. (r7567)
- Fix a bug with replacing devices in place. (r7575)
- Add a confirmation password field for dyndns. (r7576)
- If the webgui can't bind to the address specified in the GUI bind to the wildcard. Set an alert if this is done. (r7562, r7563, r7570, r7579)
- Add a save debug button in the system -> advanced GUI to ease collecting diagnostic information when shell access isn't configured. (r7592)
- Allow an interface to accept tagged and untagged packets. (r7604, r7609)
- Improvements to ataidle. (r7648)
- Reverse the list for ipv4 netmask. (r7663)
- Fix openldap authenticating against servers that require SSL/STARTTLS (r7685)
- Build python with a larger stack size. This should solve intermittent django stability issues (r7689)
- Move the USB 3 driver to a module so it can be disabled for hardware that has issues booting with the module enabled. (r7691)
- Allow the iSCSI extent file browser to show files. (r7695)
- Allow iSCSI extents to be used by one target->extent mapping. (r7697)
- Restrict the iSCSI target name to values allowed by the target and the RFC covering iqns. (r7698)
- Restart collectd properly when volumes are created or destroyed. (r7704)
- Make timezone changes take effect immediately in django. (r7720)
- Use the file browser for editing iSCSI file extents. (r7728)
- Ensure that the selection for an iSCSI file extent is a file and not a directory. (r7729)
- Allow auto-importer to work when there are zpools that contain subsets of each other's names. eg: tank and tank2 (r7732)
- Update django to 1.3.1 to address multiple security vulnerabilities. (r7745)
- Fix a bug where the system would attempt to change permissions from an unknown user to root:wheel. (r7762)
- Disable building the weekly locate database. (r7765)
Errata:
CHAP doesn't work with GlobalSAN initiators on OS X.
Upgrades from FreeNAS 0.7 aren't supported.
Mine came through quite swiftly afterwards mate, less than a month if memory serves because I used the cash to buy the extra HDD's for mine.
It's done as part of a monthly run the longest you should wait is 5 weeks.
Are they what you have in yours? Did you have any problems with them in a RAID array? I have only used the Samsung F4's and I read somewhere that WD try and make you buy their RE models for using with RAID and they make it difficult on the Blue/Green/Black lines...The WD 2gb eco drives are on special at Scan until Monday

So maybe something like a RocketRAID 2720 is the way to go, in RAID-5.teh wiki said:...raidz1 (similar to RAID-5) should be avoided, because repairing a raid puts additional stress on the other disks which might cause them to crash, losing all data in the storage pool if configured as raidz1. Therefore, with large disks one should use raidz2 (allow two disks to crash) or raidz3 (allow three disks to crash).
I would go with the upcoming PC-Q25, it looks perfect for a 4 (or 6 or 8) drive NAS.
Space for 5 (hotswappable) drives in the cage and 3 more on the tray at the bottom. I have no need for a optical drive in it so this new case is tempting me quite badly.
Quite a looker as well.
Put a Mini-ITX board in there with an Intel i5 or something with 8gb RAM, hook it up to the network and to my telly via HDMI and I have myself a NAS and a tasty little media server to boot.
