[zfs-discuss] Force file read even with checksum error
Hi guys, I have a pool made with three luns striped. After some scsi retryable messages, happened during a storage activity, zpool status start to report one checksum error on one file only. The zpool scrub find it but don't solve it, and when I try to read the file, I get an I/O error. Again, when I try to copy the file, I get only some bytes copied, and then stops, I mean this is because the next block is in error... However, I'd like to do some check on this file, especially since I am not convinced that the lun is bad and the file corrupted... Is there a way to force zfs to give me the whole file so I can compare it to my backup? Is there a way to get zfs to give more specifics on the checksum issue (i.e. which block, where in file, etc.)?

[zfs-discuss] questions about ZFS Send/Receive
Hi guys, we are proposing a customer a couple of X4500 (24 Tb) used as NAS (i.e. NFS server). Both server will contain the same files and should be accessed by different clients at the same time (i.e. they should be both active) So we need to guarantee that both x4500 contain the same files: We could simply copy the contents on both x4500 , which is an option because the "new files" are in a limited number and rate , but we would really like to use ZFS send & receive commands: AFAIK the commands works fine but generally speaking are there any known limitations ? And, in detail , it is not clear if the receiving ZFS file system could be used regularly while it is in "receiving mode": in poor words is it possible to read and export in nfs, files from a ZFS file system while it is receiving update from another ZFS send ? Clearly until the new updates are received and applied the old copy would be used TIA Stefano Sun Microsystems Spa Viale Fulvio testi 327 20162 Milano ITALY me *STEFANO PINI* Senior Technical Specialist at Sun Microsystems Italy <http://www.sun.com/italy> contact | [EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> | +39 02 64152150 ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
