摘要： A method for recovering meta-data that has been subjected to corruption is disclosed for a cache memory. Each table entry in the cache memory has an in-cache indicator for indicating whether the data unit associated therewith is stored in a cache-slot in the cache memory. A first review is conducted of the table entries for identifying in-cache table entries (those that are associated with cache-slots in the cache memory), performing a correction attempt to ensure that the meta-data in an in-cache table entry are validated and corrected, if necessary, and ensuring that the in-cache indicator is set for an in-cache table entry. A second review is conducted of the table entries to ensure that the in-cache indicator is not set for any table entry that is not an in-cache table entry or for any in-cache table entry for which the correction attempt was unsuccessful.

摘要： A method for managing data in a computer system comprises identifying a data-set that has data unit protection that is suspected of having been corrupted, suspending a data unit protection process for the data-set; deferring re-establishing the data unit protection process for the data-set until issuance of a request for an I/O operation for the data unit; and re-establishing the data unit protection process for the data-set in response to the request and before the I/O operation is conducted. The data has a data unit protection invalidity indicator for indicating that the data-set has data unit protection that is suspected of having been corrupted; and the data unit protection process is suspended in the presence of the data-set protection invalidity indicator. Meta-data protection that is suspected of having been corrupted may be used to identify a corrupted data-set.

摘要： Embodiments of the invention exploit the fact that not all portions of a logical volume may include data written by a host. Accordingly, an embodiment of the invention includes setting a designated set of bits to 1 in a meta data table when a logical volume is initialized. These bits may be referred to herein as Never Written by Host (NWBH) bits. Separately, or in combination, an embodiment of the invention includes setting a NWBH bit to 0 when data is written to the associated portion of the logical volume. Separately, or in combination, an embodiment of the invention includes reading the NWBH bit upon receiving a read command associated with the associated portion of the logical volume. If the NWBH bit is equal to 1, data is not read from the associated portion of the logical volume; if the NWBH bit is equal to 0, data is read from the associated portion of the logical volume.
摘要翻译：本发明的实施例利用了逻辑卷的并非所有部分可以包括由主机写入的数据的事实。因此，本发明的实施例包括当逻辑卷被初始化时，在元数据表中设置指定的一组位。这些位在本文中可以被称为从不由主机（NWBH）位写入。单独地或组合地，本发明的实施例包括当数据被写入逻辑卷的关联部分时将NWBH位设置为0。单独地或组合地，本发明的实施例包括在接收到与逻辑卷的相关部分相关联的读取命令时读取NWBH位。如果NWBH位等于1，则不从逻辑卷的相关部分读取数据; 如果NWBH位等于0，则从逻辑卷的相关部分读取数据。

摘要： Disclosed is an automated purchasing system that utilizes wireless purchaser identifier weight sensing shelves that wirelessly communicate with a store server. Purchasers can utilize a wireless identifier that may comprise an RFID or NFC device, such as a smart phone or tablet computer, which is placed in front of the weight sensing shelf and identifies the purchaser. The purchaser can then remove products from the shelves and the store server keeps track of the items removed. The automated purchasing system eliminates the costly and time consuming checkout process in various stores, such as grocery stores, department stores, hardware stores and other similar stores. Locked compartments and access portals can also be accessed. Also disclosed is a weight measuring hanger that comprises a hanger rod. The hanger rod employs a weight sensor that is sufficiently sensitive to detect the removal or addition of a product from the hanger rod.

摘要： Described are techniques for representing and using RAID group consistency information. RAID group consistency information for a slice of data included on a device may be obtained by mapping the slice to an index. The index is one of a plurality of indices each associated with a structure indicating RAID group inconsistencies for a different portion of slices of data of the device. If the index is not associated with a structure, it may be determined that there is no RAID group inconsistency for the slice. If the index is associated with a structure, a hint bit associated with the slice may be determined wherein the hint bit encodes summary consistency information for a plurality of slices. A determination is made as to whether the hint bit is set, and, if the hint bit is not set, it is determined that there is no RAID group inconsistency for the slice.
