Verizon Is Booting 8,5. License Plate Automatic Frame Shutter Wardrobe there. Rural Customers Over Data Use, Including Some on 'Unlimited' Plans.Verizon has decided to abruptly cut off wireless internet to some 8,5. Oracle offers a comprehensive and fully integrated stack of cloud applications and platform services. Verizon has decided to abruptly cut off wireless internet to some 8,500 rural customers in 13 states, saying their heavy data use had made it impossible to profit off. Approximately 8,5.

While we appreciate you choosing Verizon, after October 1. Verizon service area.”No option to continue, with or without reducing use of mobile data, was given. Per BGR, the issue stems from Verizon’s LTEi. RA program, in which the company pairs with 2. Verizon users get to jump on board those regional networks whenever they want, though when they use roaming data Verizon is responsible for paying the carriers’ fees. While Verizon says some of the users were using as much as a terabyte of data monthly, one family reported they had been using less than 5. Now we are left with very few choices, none of them with good service,” a member of the family told Ars Technica.

It’s OK—though I live in a small town, I know a lot of people, and I’m telling every one of them to steer clear of Verizon.”Verizon’s decision has ramifications for the regional carriers as well, which say the company encouraged them to build infrastructure to expand their service areas but is now backing out on the deal. Though US telecoms have long gotten away with the digital equivalent of murder while providing terrible service, Verizon’s decision is particularly ominous given it could soon be given free license to treat rural customers even more poorly. The Federal Communications Commission and its Donald Trump- appointed chairman Ajit Pai have recently sought to slash the agency’s standards for what it considers acceptable access to broadband, including by allowing service providers to pass off mobile service as a replacement for home internet—a decision that would disproportionately impact poor Americans.[BGR, Ars Technica]. Introduction to Oracle Solaris 1. ZFS (Zettabyte File System)What You See Is What You Get Element. Hands- On Labs Of the System Admin and Developer Community of OTN Oracle Solaris ZFS is a revolutionary file system that changes the way we look at storage allocation for open systems. This session is a hands- on tutorial on the basics of Oracle Solaris ZFS. It describes how devices are used in storage pools and considers performance and availability. It also looks at the various types of Oracle Solaris ZFS datasets that can be created and when to use each type. Participants will learn about file system snapshots, cloning data, allocation limits and recovering from common errors. In the following exercises, we will create some zpools and explore different types of virtual devices (vdevs). We will also create two different types of ZFS datasets, file systems and volumes. We will customize some properties, snapshot and clone them, and finally perform some upgrades. In the advanced section, we will look at how some of the other Oracle Solaris services, like NFS (Network File System) and FMA (Fault Management Architecture) are tied into ZFS. These exercises are meant to explore some of the possibilities. Armed with the manual pages and a group of willing assistants, you are encouraged to explore any other features of ZFS. Lab activities.

In the ZFS file sytems, storage devices are grouped into pools, called zpools. These pools provide all of the storage allocations that are used by the file systems and volumes that will be allocated from the pool. Let's begin by creating a simple zpool, called datapool. First we need some storage devices. We will create 4 files and use them for our first pool. Creating and destroying pools. Now let's create our first pool. That's all there is to it. We can use zpool status to see what our first pool looks like. NAME STATE READ WRITE CKSUM. ONLINE 0 0 0. ONLINE 0 0 0. ONLINE 0 0 0. ONLINE 0 0 0. ONLINE 0 0 0. ONLINE 0 0 0. What we can see from this output that our new pool called datapool has a single ZFS virtual device (vdev) called raidz. That vdev is comprised of our four disk files that we created in the previous step. This type of vdev provides single device parity protection, meaning that if one device develops an error, no data is lost because it can be reconstructed using the remaining disk devices. This organization is commonly called a 3+1, 3 data disks plus one parity. ZFS provides additional types of availability: raidz. We will look at some of these in later exercises. Before continuing, let's take a look at the currently mounted file systems. NOTE: In Oracle Solaris 1. ZFS filesystems consume. In case you need to see how much space is available on non- ZFS filesystem, such as mounted over the network via NFS or another protocol, traditional df(1) command exists in Oracle Solaris 1. System administrators familiar with df(1) can continue to use df(1), while using zfs list for ZFS filesystems is encouraged. NAME USED AVAIL REFER MOUNTPOINT. K 1. 4. 1G 4. 4. 9.

The default mountpoint is derived by the name of the pool, but can be changed if necessary. With ZFS there's no need to create a file system, make a directory to mount the file system. It is also unnecessary to add entries to /etc/vfstab. All of this is done when the pool is created, making ZFS much easier to use than traditional file systems. Before looking at some other types of vdevs, let's destroy the datapool, and see what happens. NAME USED AVAIL REFER MOUNTPOINT. G 5. 4. 6. G 3. 9K /rpool. ROOT 6. 3. G 5. 4. 6. G 3. 1K legacy.

G - . All file systems in the pool have been unmounted and the pool has been destroyed. The devices in the vdev have also been marked as free so they can be used again. Let's now create a simple pool using a 2 way mirror instead of raidz. NAME STATE READ WRITE CKSUM. ONLINE 0 0 0. ONLINE 0 0 0. ONLINE 0 0 0. ONLINE 0 0 0. No known data errors. Now the vdev name has changed to mirror- 0 to indicate that data redundancy is provided by mirroring (redundant copies of the data) instead of parity as it was in our first example. What happens if you try to use a disk device that is already being used by another pool? Let's take a look. The usage error indicates that /dev/dsk/disk. The - f flag to the zpool create command can override the failsafe in case datapool is no longer being used, but use that option with caution. Adding capacity to a pool. Since we have two additional disk devices (disk. ZFS pool. # zpool list datapool. NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT. M 8. 9. 5. K 4. 92. M 0% 1. 0. 0x ONLINE - .

See that a second vdev (mirror- 1) has been added to the pool. Let's look at the zpool listing now. NAME SIZE ALLOC FREE CAP DEDUP HEALTH ALTROOT. M 9. 2. 5. K 9. 84. M 0% 1. 0. 0x ONLINE - . Our pool has grown from 5. MB to 1. GB. # zfs list datapool. NAME USED AVAIL REFER MOUNTPOINT. K 9. 52. M 3. 1K /datapool. Notice that you don't have to grow file systems when the pool capacity increases. File systems can use whatever space is available in the pool, subject to quota limitations, which we will see in a later exercise. Importing and exporting pools.
